     A Catalog of Available X.500 Implementations

Status of this Memo

   Thismemo provides information for the Internet community.  It does
   not specify an Internet standard.  Distribution of this memois
   unlimited.

Abstract

   The goal of this document isto provide information regarding the
   availabilityand capability of implementations of X.500.  Comments
   and critiques of this document, and new or updated descriptions of
   X.500 implementations are welcome.  Send them to theDirectory
   Information ServicesInfrastructure (DISI) Working Group
   (disi@merit.edu) or to the editors.

1.  Introduction

   Thisdocument catalogs currently available implementations of X.500,
   including commercialproducts and openly available offerings.  It
   contains descriptions of Directory System Agents (DSA), Directory
   UserAgents (DUA), and DUA client applications.  Thelatter can
   include suchapplications asbrowsers, DSA management tools,or
   lightweight DUAs that employan application-level protocol to
   communicate with a DUA (which then in turn communicates witha DSA)
   to support user service.  Section 2 of this documentcontains a
   listing of implementations cross referenced by keyword.  This list
   willaid in identifying particular implementations that meetyour
   criteria.

   To compile this catalog, theDISI Working Group solicited input from
   the X.500 community by surveying several Internet mailing lists,
   including: iso@nic.ddn.mil, isode@nic.ddn.mil, osi-ds@cs.ucl.ac.uk,
   and disi@merit.edu.

   Readers are encouraged to submit comments regarding both theform and
   content  ofthis  memo.  New submissions are alwayswelcome.  Please
   direct inputto the parties as described in the Status of  this  Memo
   section.  DISI will produce new versions of this document when a suf-
   ficient number of changes have been received.  Thiswill  be  deter-
   mined subjectively by the DISI chairperson.

1.1  Purpose

   The growth of existing X.500pilot activities (e.g.,White Pages
   Pilot Project) and the advent of newpilots (e.g., ARRNet Directory
   Services Project, NIST/GSA Pilot Project) are signals that X.500 is a
   viable directory service mechanism for the Internet community.  A
   goalof DISIis to enable the continued growth of X.500 by lowering
   the lack-of-information barrier.  This document takes one step toward
   thatgoal byproviding an easily accessible source of information on
   X.500 implementations.

1.2  Scope

   Thisdocument contains descriptions of either commercially or freely
   available X.500 implementations.  Itdoes not provide instructions on
   how to install, run,or manage theseimplementations.  Because the
   needs and computing environments of each organization differvastly,
   no recommendations are given.  The descriptions and indices are
   provided to make thereadersaware of existing options and to enable
   moreinformed choices.

1.3 Disclaimer

   Implementation descriptions were written by implementors andvendors,
   and not by the members of DISI.  Although DISI has worked with the
   description authors to ensure readability, no guarantees canbe made
   regarding the validity of descriptions or the value of said
   implementations.  Caveat emptor.

1.4  Overview

   Section 1 contains introductory information.

   Section 2 contains alist ofkeywords, theirdefinitions, and a cross
   reference ofthe X.500 implementations by these keywords.

   Section 3 contains the X.500implementation descriptions.

   Section 4 lists the editors'addresses.

1.5  Acknowledgments

   The creationof thiscatalogwould not have been possible without the
   efforts of the description authors and the members of the DISI
   Working Group.  The editors thank you for your hard work and
   constructivefeedback.  A special thanks is also extended tothe
   members of the NOCTools Working Group.  The "NetworkManagement Tool
   Catalog" (RFC-1147) served as a valuable example.  Bob Stineand Bob
   Enger made key suggestions that enabled us to learn from their
   experiences.

   The efforts of the editors were sponsored byDefenseAdvanced
   Research Projects Agency Contract Number DACA76-89-D-0002 (Field
   Operational X.500 Project), and U. S. Department of Energy Contract
   Number DE-AC03-76SF00098.

2.  Keywords

   Keywords areabbreviated attributes of the X.500 implementations.
   The list of keywordsdefinedbelow was derived from the
   implementation descriptions themselves.  Implementations were indexed
   by akeywordeither as a result of: 1) explicit, notimplied,
   reference toa particular capabilityin the implementation
   description text, or2) input from the implementation description
   author(s).

2.1  Keyword Definitions

ABSTRACT

   Alliance OSIincludes XDS (API), DUA, DSA and DIB all as separate
   components.

   Touch's X.500 products have been designed for complete portability to
   any operating systemor hardware environment.  The protocolsinclude
   DAP and DSP of the OSI X.500specification along with the required
   XDS,DUA, DSA and DIB components.  In addition to X.500, Touch sup-
   plies other OSI protocol layers including: ROSE, ACSE, Presentation,
   Session and any of the OSI lower layers (Transport, Network along
   withRFC-1006).  Touch also suppliesother application layerproto-
   colssuch asX.400, FTAM, CMIP (and general network management), etc.

   The AllianceOSI X.500 is compliant with theCCITT X.500 1988 Recom-
   mendations. The ROSE/ACSE/Presentation/Session stackcan be option-
   allyprovided by Touch.

   The DUA may represent a single user,or may represent a group of
   users.  It may be attached to a given DSA within thesame system but
   is also capable of invoking operations in Touch's orany other
   vendor's compliant DSA on a remote system.  The binding operation
   requires theuser togive a distinguished name and password in order
   for the Directory toidentify the user.  Once an associationis esta-
   blished the user mayinvoke the following operations: READ, COMPARE,
   ABANDON, LIST, SEARCH, ADD_ENTRY, REMOVE_ENTRY, MODIFY_ENTRY,
   MODIFY_RDN.









DISI Working Group               [Page 15]



RFC 1292   Alliance OSIX.500    January 1992


   Due to the fact thataccess to the physical disk is in mostcases  a
   blocking  operation(synchronous)  Touch  has separated thedatabase
   processing (I/O process) from the DSA protocol entity.  This separa-
   tionallows the DSA entity to continue processing during thefrequent
   database accesses from the DSA. The DSA supports  all  the  Directory
   operations  as specified in the CCITT X.500 specification.  Chaining,
   Referral andMulticasting are provided and supportedin theAlliance
   OSIDSA.   The DSA supportsall theservicecontroloptionsincluded
   in the operation command arguments.Filtering  conditions  are  sup-
   ported via the FILTER in theSEARCH operation.

   The AllianceOSI X.500 product supports all the NISTdefinedmanda-
   toryX.500 and X.400object classes and attributes.

   Alliance OSIX.500 supports all the mandatory Directory attribute
   types (and their associated abstractsyntaxes) in the NIST Directory
   implementation profile. Touch has extended the Directory andallows
   users to define private attributes.This means thata user can util-
   ize the Alliance OSIDirectory for ageneralpurpose, user defined
   database activity.

   Touch provides a full set ofadministration and Directory management
   facilities.

   Touch is in the process of integrating the X.500 product with the
   Worldtalk 400 product. Worldtalk 400is Touch's end user X.400 mes-
   sageswitch,providing gateways between proprietary mail systems
   (SMTP, Microsoft Mail, MHS, cc:mail,etc.) and X.400.  X.500is a key
   component for a messaging network.

COMPLETENESS

   Strong Authentication is notsupported however Simple Authentication
   is supported.

INTEROPERABILITY

   No interoperability testing has beencompleted as ofyet.

PILOT CONNECTIVITY

   Numerous OEMs are using the AllianceOSI X.500 product in product
   development as well as in pilot networks.

CAVEATSAND GENERAL LIMITATIONS

   Currently the Alliance OSI X.500 DIBhas only been validatedwithin a
   UNIXFile System.  The protocol components are portable as is the
   interface between the DSA and the DIB.

INTERNETWORKINGENVIRONMENT

   Alliance OSIX.500 can be utilized over TCP/IP and/or OSI Transport
   on LANs and WANs.  CurrentlyX.500 has only been verified over OSI,
   however other Alliance OSI application layers have been configured
   overa RFC-1006 which is available as part of the Alliance OSI pro-
   ductline.

HARDWARE PLATFORMS

   Alliance OSIhas been portedto numerous platforms ranging from IBM
   Mainframes MVS to Apple Macintosh.  For UNIXenvironments Touch has
   portations for 386 AT/Bus, SUN-3 and4, Mips, and HP.

SOFTWARE PLATFORMS

   As stated above, theAlliance OSI product have been ported to
   numerous systems.  In the UNIX environment the X.500productexists
   on SUN OS 4.0 and greater, Mips RISCOS, Interactive386 andHP-UX.

LAST MODIFIED

   November, 1991

KEYWORDS

   API,DSA/DUA, Free, Limited Functionality, Multiple Vendor Platforms,
   Requires ISODE, OSI Transport, RFC-1006, Sun, UNIX

ABSTRACT

   The implementation consists of a setDUA library routines, aterminal
   interface, and a DSA. The implementation wasdeveloped in C on Sun 3
   workstationsunder the UNIX operating system. All underlyingservices
   are providedby the ISODE development package. The development pack-
   age is also used forencoding and decoding ASN.1 data as well as for
   other data manipulation services. Using the ISODE package the imple-
   mentation can be runover both OSI and TCP/IP protocols.

   The DSA provides full support for both DAP and DSP protocols, confor-
   mantwith ISO 9594/CCITT X.500 standards. The DIB ismaintained using
   a locally developed relational database system. The interface to the
   database system consists of a set ofSQL-like C functions.  These are
   designed to allow straightforward replacement of thelocal database
   system with a more powerful commercial system. To achieve better per-
   formance several options aresupported that permit loading of
   selected portions ofthe database into core.When these options are
   selected data can beretrieved more quickly from in-core tables; all
   modifications to theDIB aredirectly reflected in the in-core tables
   and the database.

COMPLETENESS

   To date the Read, Compare, List, AddEntry, and Remove Entryopera-
   tions have been implemented and are supported over both DAP and DSP;
   aliasing andreplication arealso supported. The version under
   current development (available January '92) includessimple authenti-
   cation, access control, and the Search operation. The modifyopera-
   tions and Abandon are not supported and there is no support for
   schema checking.

RFC 1292 Custos    January 1992


INTEROPERABILITY

   Havesuccessfully interoperated withQUIPU and OSIWARE over the DAP.
   No DSP interoperability testing has been done.

PILOT CONNECTIVITY

   Not tested.

BUGS

   Sometestingin the near term futurewill bedone totry to identify
   these, but presentlyit's not possible to give an accurate list of
   bugs.

CAVEATSAND GENERAL LIMITATIONS

   No limitations on file sizes, etc. The only side effects to creating
   large files should be in thearea ofperformance. Specifically,
   optimizationrequires loading parts of the DIB in core so greater
   memory requirements will be necessary for achieving better perfor-
   mance with alarge database. Any platform the implementation can be
   ported to (generallyany platform ISODE can be ported to) should sup-
   portall features.

INTERNETWORKINGENVIRONMENT

   RFC-1006; TP4/CLNP (SunLink OSI) over 802 and X.25 (SunLink X.25).

HARDWARE PLATFORMS

   It has been run on Sun-3, but there are no known reasons whyit
   should not run on any hardware running the ISODE software.

SOFTWARE PLATFORMS

   It requires UNIX andthe ISODE software package.  It's been developed
   and tested with ISODE version 6.0 and Sun OSversion4.1.1.Uses a
   locally developed relationalDBMS that should be easily replaceable
   withcommercially available relational systems.

AVAILABILITY

   While under continuing development, availability of the implementa-
   tionis limited to organizations making appropriate arrangements with
   NIST.  The implementation will be publicly availablewhen development
   is completed.

ABSTRACT

   DCE/GDS (DistributedComputing Environment/Global Directory Service)
   was based onthe original Siemens DIR.X product. It supportsfull DUA
   and DSA functions for globally unique identifications and for loca-
   tionof objects in the network. It also provides functions to answer
   queries (both yellow-page and white-page) about objects and attribute
   information. The software implements full DAP and DSP protocols
   specified inX.519.An ASN.1 compiler and required ACSE, ROSE,
   presentation, session and RFC-1006 protocolsimplementationsare also
   included.

   The product has beensuccessfully participated in X.500 Cebit Intero-
   perability tests at 1990 and1991 Hanover Fairs. It also intero-
   perates withthe ISODE QUIPUX.500 implementation.

COMPLETENESS

   Compliant with EWOS Agreements whichis being harmonized with OIW
   Agreements.

   Strong authentication in X.509 is not yet implemented. (Password
   scheme is currently used.)

   Consists of both DUAand DSAimplementation according to the88 CCITT
   X.500 and ISO 9594 standard. The X/Open standard XDS (version 1.0)
   and XOM (version 2.0) interface libraries are also provided. XDS and
   XOM interfaces are also usedto access DCE/CDS (Local Cell Directory
   Service) transparently. A GDA (Global Directory Agent) serves as the
   gateway between the DCE CDS and GDS.

ABSTRACT

   DE (Directory Enquiries) is intendedto be asimple-to-use interface,
   suitable forthe naive user,and suitable for running as a public
   access dua to provide lowestcommon denominator access to the Direc-
   tory.  It isa scrolling interface and will thus runon dumbtermi-
   nals, even teletypes!  The user is asked to fill in up to 4 questions
   per query: person's name; department; organization; country. The
   prompts are very verbose -- the intention isthat the user should not
   be able get stuck, and information on how toget into the help system
   should always be on the screen.  Thehelp screens (of which there are
   15) are aimed at thenon-technical user.  Whilst theoutwards appear-
   anceof the interface is simple, a lot of attention has being given
   to mapping the strings the user enters onto X.500 operationsin such
   a way that the interface seems to dothe "right thing".  An important
   characteristic is the way the interface tries a series of searches,
   gradually relaxing the matching criteria from exact (in somesense),
   to good, through to "fuzzy". A considerableamount of configuration
   is possible to present the results in locally acceptable formats.

   DE was funded by theCOSINE PARADISEproject, and DEis usedas the
   PARADISE public access dua.You cantest the software by telnet to
   128.86.8.56 and logging in as dua --no password required.

COMPLETENESS

   The interface is a querying engine only.

INTEROPERABILITY

   DE is built with theISODE software (release7.0).  Its interopera-
   bility relies on thecorrectness of the Quipu libraries.

PILOT CONNECTIVITY

   The interface is in use as the COSINE Central DUA Service, and is
   usedby a number of UK institutions as a public access dua (usually
   overX.29).It is able to query entries in pilots throughout the
   world.  It is not able to query for entries which are in organiza-
   tions beneath locality entries undercountryentries.  It isnot pos-
   sible to query for people who do notwork for organizations. The
   interface only searches for entries of the followingtype: organiza-
   tions, organizational units,people,roles, and rooms.

BUGS

   Sendbug reports to:

   p.barker@cs.ucl.ac.uk
   helpdesk@paradise.ulcc.ac.uk

CAVEATSAND GENERAL LIMITATIONS

   DE tries to cater well for the general case,at the expense of not
   dealing withthe less typical.  The main manifestation of this is
   thatthe current version will not query under localities immediately
   under the country level.

   It is not possible to display photographs orreproduce soundattri-
   butes.

INTERNETWORKINGENVIRONMENT

   Sameas ISODE.  ISODE supports TCP/IP, TP0, and X.25.

HARDWARE PLATFORMS

   Should be the same as ISODE in general.

SOFTWARE PLATFORMS

   DE requires the ISODE (current release 7.0) libraries.

AVAILABILITY

   DE is openlyavailable as part of ISODE and as part of the COSINE DUA
   package.   Availableby FTAMand FTP, sourcecode freely available.

ABSTRACT

   The DIXIE protocol is used to give X.500 access to platformsthat
   haveonly TCP/IP access.  The DIXIE server is an intermediate proto-
   col server that communicateswith Internet clients on one side using
   a text-basedUDP/TCPprotocol and anX.500 DSA on the other side
   using DAP.  The protocol is fully described in RFC 1246.  A subset of
   the X.500 DAP is exported tothe clients through theDIXIE protocol.
   There is a DIXIE APIprovided in theform ofa library of C-callable
   routines.

   The DIXIE protocol and server are being usedby the following
   products/projects:

     UD, a simple command line white pages DUA for Unixmachines (dis-
     tributed with the DIXIE server)

     maX.500, awhite pages DUAfor theMacintosh (available from the
     same placeas the DIXIE server)

     Network monitoringof DSAsby our Network Operations Center

     Lookup anddisplayof caller identification based on telephone
     caller ID (using ISDN).

COMPLETENESS

   The DIXIE protocol does not support access to all X.500 features and
   operations.All DAPoperations except Abandon are supported.  Gen-
   eralsearches (including multiple component searches) are supported.
   The DIXIE protocol supports none andsimple authentication.A subset
   of the service controls are supported.

RFC 1292 DIXIE    January 1992


INTEROPERABILITY

   The current implementation of the DIXIE server workswith the QUIPU
   DSA and DAP library.

PILOT CONNECTIVITY

   The DIXIE server hasbeen tested in the Internet andPARADISE pilots.
   It provides full DUAConnectivity subject tothe limitationsdis-
   cussed aboveunder completeness.

BUGS

   There are noknown outstanding bugs. But reports should be sent to
   x500@umich.edu.

CAVEATSAND GENERAL LIMITATIONS

   None, aside from those mentioned above undercompleteness.

INTERNETWORKINGENVIRONMENT

   DIXIE clients use TCP or UDPto communicate with theDIXIE server.
   The DIXIE server uses RFC-1006 with TCP/IP to communicate with the
   DSA,though other transport mechanisms for DSA communicationshould
   be possible.

HARDWARE PLATFORMS

   The DIXIE server is known torun on Sun 3, Sun 4, and DEC 3100 plat-
   forms.  It should run on anyUNIX platform.The DIXIE library is
   known to runon the same platforms, and alsoon the Macintosh.

SOFTWARE PLATFORMS

   The DIXIE server andlibraryis known to rununder SunOS 3.5, SunOS
   4.1.1, Ultrix 4.1 and 4.2.  The DIXIE library also runs on the Macin-
   toshSystem Software6 or later.

AVAILABILITY

   Thissoftware is openly available.  It may be obtained by anonymous
   FTP from terminator.cc.umich.edu in the directory ~ftp/x500.Documen-
   tation on the DIXIE protocolis provided along with the source code,

ABSTRACT

   DS-520 X.500Distributed Directory Services for UNIXSystem V and
   DS-521 X.500Directory User Agent (DUA) for UNIX System V form an
   integral part of theRetix OSI Networking Products family.  Designed
   for systems vendors,public carriers, and other OEMs, DS-520is a
   complete high-performance implementation of X.500 insource code
   form, including a DUA, DSA Manager (DSAM), and DSA.DS-521
   represents asubset of this product offering. It provides the DUA
   portal into the directory, which, for example, meetsthe needs of
   software vendors whoplan toprovideapplication packages with X.500
   Directory interaction capabilities. Within these twoofferings, the
   DUA possesses two forms of interface. The first form, the DUA with
   UserInterface, provides an interactive character-based userinter-
   facefor users of Directory services.  The user agent provides access
   to the Directory viabasic Directoryservicerequests. The second
   form, the DUA with Programmatic Interface provides astandardized
   programmaticinterface to application programs that must access
   Directory information. The interfaceis conformant to the X/Open
   Object Management (XOM) and X/Open DirectoryServices (XDS) stan-
   dards. This component provides all functionality related to Directory
   access and general OSI services downto the session layer. The DSAM
   provides an interactive character oriented user interface toa Direc-
   toryadministrator.The DSAM provides management functions either
   local to or remote from a DSA. Both the DUA and the DSAM areuseful
   in the training, management,and manipulation of Directory entries
   maintaining operational and user attribute information. The DSA main-
   tains Directory database informationand provides users the ability
   to read/compare, modify, search, andmanage entries within the data-
   base. It maintains all or fragments of the DirectoryInformation Base
   (DIB) and provides abstract service ports for DUAs and DSAs over DAP
   and DSP protocols respectively.

RFC 1292     DS-520, DS-521    January 1992


COMPLETENESS

   DS-520 represents a completeimplementation of the 1988 X.500 Recom-
   mendations with the exception of strong authentication as outlined in
   X.509. It isconformant to NIST, EWOS, and UK GOSIP Directory pro-
   files. It provides session through application layerprotocol support
   and hence incorporates ROSE,ACSE, Presentation, andSessionwithin
   its product stack. In addition to including all the attribute types,
   syntaxes, and objectclassesdefinedin X.520 and X.521, theDS-520
   includes support forthose specifiedin the 1988 X.400 Recommendation
   X.402, AnnexA. Remote on-line management ofthe DSAis supported by
   means of Network Management Forum CMIP.

   DS-521 represents a completeimplementation of the X/Open Object
   Management (OM) and X/Open DirectoryServices (XDS) standards. It
   alsoincorporates session through application layer protocolsupport
   and thus includes ROSE, ACSE, Presentation, and Session within its
   product stack.

INTEROPERABILITY

   The DS-520 has been tested to interoperate with Banyan (DAP), CDC
   (DSP), IBM, ICL, OSIWare, Nixdorff, Unisys (DSP), Wollongong(DAP),
   and 3-Com (DSP).

   The DS-521 subset has undergone no separate interoperabilitytesting.

PILOT CONNECTIVITY

   DSA Connectivity provided bythe DS-520: TheDSA provides complete
   support for the X.511 Abstract Service Definition, the directoryAc-
   cessAC and the directorySystemAC defined in the X.519 Protocol
   Specifications, and the Distributed Directory defined in theX.518
   Procedures for the Distributed Directory. Itsupports all the object
   classes, attribute types, and attribute syntaxes defined in X.520 and
   X.521. It does not support the Internet DSP however.

   DUA Connectivity provided byboth the DS-520and DS-521: TheDUA pro-
   vides complete support for the X.511Abstract Service Definition and
   the directoryAccessAC defined in theX.519 Protocol Specifications.
   The DUA withUser Interface supportsonly a subset of the X.500
   attributes and object classes defined in X.520 and X.521. The DUA
   withProgrammatic Interface,however, does support all the object
   classes, attribute types, and attribute syntaxes defined in these two
   recommendations.

BUGS

   Product Action Requests (PARs) stemming externally from customers and
   internally from customer service andqualityassurance engineers are
   generated and published in the form of weekly reports. A description
   and status of these PARs areprovided to customers possessing
   software maintenanceagreements.

CAVEATSAND GENERAL LIMITATIONS

   DS-520 and DS-521 are sourcecode products ported toUNIX System V
   Release 3 and 4. Makefiles to generate the system are provided for
   the AT&T System V, SCO, and Interactive UNIXsystems.

INTERNETWORKINGENVIRONMENT

   DS-520 and DS-521 offer two main compile time configuration options
   and hence internetworking configurations. Inthe first of these, they
   interface tothe UNIX SystemV Transport Library Interface (TLI).
   The TLI provides a path between the session layer ofa UNIX OSI
   application process and an OSI transport provider installed in the
   UNIXkernel.The latter transport provider may take the formof a
   Retix Unix LAN (LT-610) or WAN (WT-325) transport product. The second
   mainoption utilizesthe UNIX SystemV ACSE/Presentation Library
   interface (APLI and the A/P Library), which providesOSI ACSE and
   Presentationlayer services.The Retix AP-240 Presentation syntax
   manager product serves to map the standard Retix Presentation layer
   interface tothe AT&T APLI. The APLIupper layers services may be
   provided by the Retix UL-220product. UL-220is the Retix implementa-
   tionof the AT&T Open Networking Platform Upper Layer Services module
   and includesthe A/Plibrary, as well as theOSI ACSE, Presentation,
   and Session services.

   DS-520 and DS-521 may also run on top of theTCP/IP stack bymeans of
   the Retix MP-120 product. MP-120 is a STREAMS based driver that
   implements RFC-1006 and thusallows OSI applicationsto run over a
   network based on theInternet suite of protocols (TCP/IP). Its main
   function provides a conversion between the TCP stream to thedata
   packets required by OSI Transport Class 0 protocol and vice versa. As
   partof thisprocess, it converts TCP/IP 32-bit addresses tohex

ABSTRACT

   HP'sDistributed Directory Software is a fully distributed Directory
   thatsupports both the DAP and DSP protocols, which were specified in
   the 1988 CCITT/ISO X.500 documents.Besidesimplementing the stan-
   dard, we have also put in proprietary accesscontroland replication.
   These additional features will be migrated to the standard definition
   at the time that they are stable.  Users areable todefine their own
   attributes, objects classes and DIT structure rules.

   In order to make this software easy to use aset of menu driven
   screens havebeen provided.There are easy to use data access and
   datamanagement screens.  For systemadministrators,these is also a
   set for screens thatare used to help configure the servers and
   manage the schema. Startup and Shutdown utilities are also included.

   For application developers an X/Open-APIA XDS API isprovided, along
   withsome helper routines that help reduce development time. The XDS
   API includesthe following functions:

   Bind
   Read
   Search
   Add
   Remove
   Unbind
   Version

   A subset of the X/Open-APIA Object Management (XOM) functions are
   available thru the interface.  The subset are those that areneces-
   saryto perform the directory operations.

   For bulk operations a batch interface is also available.

ABSTRACT

   OSI-DSA provides a DirectorySystem agent for controlled access to
   the OSI Directory Information Base.It provides full support for the
   joint ISO/IEC IS-9594 International standardand CCITT X.500Recom-
   mendations 1988 protocols necessary for implementingthe Directory
   Information Base distributedacross a numberof DSA's.

   The product also includes anAdministration User interface program,
   to allow a human administrator to construct and maintain thelocal
   Directory Information.

   Specific features provided by the Directory System Agent include:

       (i)    Support of the directoryAccessAC and directorySystemAC
      application contexts (i.e. both DirectoryAccess Protocol
      (DAP) andDirectory System Protocol (DSP)

       (ii)   Bind Security levels of none and simple unprotected.

       (iii)  Capability of acting as afirst level DSA.

   The present OSI-DUA does notprovidefor the automatic  handling  of
   referrals  by  the  interface library. However interface routines are
   provided which allowreferrals to beacted upon by the userapplica-
   tion.

   The present OSI-DUA providesa proprietary C programming  interface.
   An XOpen XDSconformant interface iscurrently underdevelopment.

INTERNETWORKINGENVIRONMENT

   OSI-DUA runsover all communicationsenvironments supported by the
   Unisys OSI stack product (see Software platforms). Currentlythese
   support TP0,TP2, TP3 and TP4 over X.25 and TP4 overCLNP on802.3
   and X.25.  Support for RFC1006 over TCP/IP is under development.

HARDWARE PLATFORMS

   The product is currently available on all Unisys Unix 6000 Series
   machines.

   Source code is available forportation to non-Unisysplatforms.

SOFTWARE PLATFORMS

   The product is distributed and supported forUnix System V.3and Unix
   System V.4.

   On Unix V.3,it requires theUnisys Application PresentationService
   OSI stack software (APS), and UnisysTransport Network Service
   software (TNS).  On Unix V.4, it requires the integrated Unisys OSI
   stack software product (STK).  Theseservices are accessed via the
   ROSLI (ROSE)and APLI (ACSE)programming interfaces which are
   currently the subject of standardization efforts by XOpen and Unix
   International.

ABSTRACT

   POD (POpup Directory) is an X.500 DUA interface for the X Window Sys-
   tem. POD isa firstattemptat a multiwindow directory tool. It
   offers a simplified interfaces to the basic X.500 operationsof read,
   search, listand modify entry.

   POD does notprovideany sophisticated access to theDSA.  Operations
   are performed synchronously. The Directory is thus presented as is,
   i.e. a hierarchicaltree ofinformation, with the user required to
   "navigate" the DIT in order to locate required information.

   POD is available as part of the ISODE release from version 6.0
   onwards.

COMPLETENESS

   88 standard:strong authentication not implemented

INTEROPERABILITY

   Believed to be compliant, though untested.

PILOT CONNECTIVITY

   DUA Connectivity: POD is in use in many directory pilots, certainly
   including PARADISE and the Internet.

CAVEATSAND GENERAL LIMITATIONS

   psiwp is nota general-purpose DUA. It was designed to be a special-
   purpose front-end for performing White Pagessearches and thus, in
   the interests of simplification, does not provide the full range of
   functionality supported by the X.500standard. A Directory Assistance
   server (available aspart ofthe ISODE distribution)must also be run
   by sites that do notwant torun psiwp against either of thetwo
   White Pages Pilot Project service machines, wp1.psi.net and
   wp2.psi.net.

INTERNETWORKINGENVIRONMENT

   Runson Macintoshes as a Finder or MultiFinder application.

HARDWARE PLATFORMS

ABSTRACT

   QUIPU is part of theISODE which is an openly available implementa-
   tionof the upper layers of OSI.  QUIPU provides a X.500 Directory
   System Agent(DSA) and a setof Directory User Agents (DUA) aimed at
   different terminal types andmodes of interaction

   QUIPU was first publicly demonstrated at ESPRIT in November 1988.
   QUIPU is being used extensively in the European PARADISE project, the
   White Pages Pilot Project and the Australianpilot.A QUIPUDSA is
   being used at the ROOT node of the Pilot DITand is being used as
   mostcountrylevel DSAs.

   QUIPU provides its own solutions to area notspecified by the 1988
   standards such as replication and access control.

COMPLETENESS

   QUIPU is aligned to the 1988ISO IS and the NIST OIWDirectory Imple-
   mentors Guide Version 1, with the following exceptions:

       Strong authentication isnot implemented.

       QUIPU does not enforce the bounds constraints onattributes,
       filters or APDU size.

       T.61 string formatting characters are not rejected.

       If a DN is supplied withno password in an unprotected simple
       bind, QUIPU doesnot always check to seeif the DN exists.  If
       the DSA connected to cansay authoritatively theDN doesnot
       exist, the association is rejected.  However, ifa chainopera-
       tion is requiredto check the DN, the bind IS allowed.



DISI Working Group               [Page 65]



RFC 1292 QUIPU    January 1992



       When comparing attributes of UTCtime syntax, if the seconds field
       is omitted, QUIPU does not perform the match correctly (i.e., the
       seconds field inthe attribute values should be ignored,but  are
       not).

       QUIPU always supplies the optional Chaining argument ``origina-
       tor'' even if the CommonArgument``requestor'' is used.

       QUIPU always supplies the optional Chaining argument ``target''
       even if the baseobject in the DAP arguments is the same.

       The object class``without an assigned object identifier'' is not
       recognized unless the ``alias'' object class is also present.

       Non Specific SubordinateReferences are never followed by a QUIPU
       DSA, butthey are passedon correctly tothe client if generated.

INTEROPERABILITY

   QUIPU has interworked with anumber of otherimplementations, and has
   no know problems in such interworking.

PILOT CONNECTIVITY

   QUIPU is in use in many directory pilots, certainly including PARAD-
   ISE and the White Pages Pilot Project.

BUGS

   Problems should be reported to quipu-support@cs.ucl.ac.uk.

CAVEATSAND GENERAL LIMITATIONS

   None.

INTERNETWORKINGENVIRONMENT

   QUIPU users TP0 overX.25, CONS and TCP (using RFC-1006) or TP4 over
   SunLink OSI.

   The DSA knows about the problems of unconnected networks andmakes
   chain/refer choices based onthe network connectivity.  Using this an
   X.25only DSA can access data from an Internet only DSA by chaining
   operations through aDSA connected to both networks.

   API,Bull, Commercially Available, DEC Ultrix, DSA/DUA, HP, IBM PC,
   IBM RISC, Multiple Vendor Platforms,Philips, RFC-1006, Siemens, Sun,
   UNIX, X.25

ABSTRACT

   UCOM.X 500 includes a Directory System Agent(DSA), a directory
   access API, and a set of Directory User Agents (DUAs) for different
   terminal types. UCOM.X 500 is a commercial product based on PIZARRO,
   the researchprototype developed at INRIA byChristian Huitema's
   team.

   Somecharacteristicsof the DSA are:

       - The DAP and DSP protocols are providedconformant withthe 1988
       CCITT X.500 recommendations.

       - The DIB is maintained in ASN.1encodedformat in the Unix file
       system. Utilities are provided to load and dump the DIB from and
       to ASCIItext files.

       - The DIT structure is held in main memory. Additionally, fre-
       quently used attributes may be held in inverted tables in memory
       to speedup searches.

       - Knowledge management: knowledge on managed domains is stored in
       UCOM.X specific attributes of the DSA entries.

       - All X.500 (88)as wellas someX.400 (88) object classes,
       attributes and syntaxes are supported. Users maydefine their own
       classes and attribute types.

       - Schemamanagement: object class and attribute definitions are
       enforced.

       - Simpleauthentication is provided; strong authentication is not
       currently supported.



DISI Working Group               [Page 73]



RFC 1292       UCOM.X 500    January 1992


       - Accesscontrol: private mechanisms areprovided to allow access
       control lists tobe specified for parts of the DIT, to control
       modifications, and to specify access restrictions on attributes.

   The UCOM.X 500 API provides the DAP protocolto applicationsaccess-
   ing the Directory. It is a synchronous API which automatically
   manages referrals. Several DUAs using the API, are available. These
   include command lineand full screeninterfaces for users with ordi-
   naryterminals, and an X-Windows user interface (12/91). An X/Open
   XDS API willbe offered shortly.

   UCOM.X 500 is used by Frenchresearch centers involved in PARADISE, a
   COSINE project. A distributed application tocontroldocument
   transfer in a large French hospital,has been built on the UCOM.X 500
   API.It is being used for distributed applications management in the
   French Post Office.

COMPLETENESS

   UCOM.X 500 conforms to 1988 X.500 series of recommendations,as
   specified inparagraph 9 of X.519, with the exception of strong
   authentication.

INTEROPERABILITY

   Interoperability tests with other implementations, e.g. QUIPU, have
   beenmade inthe PARADISE project. UCOM.X 500 is used in theFrench
   PARADISE pilot.

PILOT CONNECTIVITY

   DSA and DUA connectivity to the PARADISE pilots.  See caveats.

BUGS

   UCOM.X 500 is a commercial product. As such,it is supportedand bugs
   are fixed when detected. Bugreportscan be sent to our support team
   via electronic mail.

CAVEATSAND GENERAL LIMITATIONS

   The DIT structure isstored in main memory which means that the order
   of magnitudeof the number of objects supported per DSA is 10,000. By
   1992100,000objectswill besupported.

   Not all syntaxes defined in the COSINE and Internet Schema are
   currently supported,and theDUAs donot display photo attributes.
   The InternetDSP is not supported.

   top of the DIXIE protocol (describedin RFC 1246).  ud was developed
   to run underUnix and is currently in beta release within U-M staff
   and a few other places that have heard of it.

   Features include theabilityto display and modify the following
   attributes: title, description, commonName, uid, mail, postalAddress,
   homePostalAddress, telephoneNumber, facsimileTelephoneNumber, home-
   Phone.

COMPLETENESS

   ud uses the DIXIE protocol to accessX.500 and thus is subject to the
   samecompleteness restrictions as DIXIE.  Itprovides Read, Search,
   and Modify capabilities.

INTEROPERABILITY

   Works with the DIXIEserver,which works with the QUIPU DSA and DAP
   library.

PILOT CONNECTIVITY

   It has been tested (in conjunction with the DIXIE server) inboth the
   Internet andPARADISE pilots.

BUGS

   No outstanding bugs are known.  But reports should be sent to
   x500@itd.umich.edu.

   Vendor Platforms, RFC-1006, Sun, X.25

ABSTRACT

   VTT X.500 contains afull distributed DSA and a subroutine call to
   dua ( call_dua(parameters)).This subroutineis linked to user's pro-
   cess.  Thereare twoways for dua tocommunicate with our DSA called
   dsacvops: a fast communication through shared memoryfor duaand dsa
   in the same computerand a complete OSI-stack for communicating in
   DAP-protocolwith remote dsa's whichcan be any implementation of
   X.500 dsa, not necessarily dsacvops. DSA communicates with other
   dsasthrougha full OSI-stack with protocol DSP or with a shorter
   stack when both dsasare dsacvops-processes. dsacvops contains a
   special purpose database DIB. VTT X500 contains caching of read and
   search results, access controls (as in AnnexF of X.501), object
   classes and attribute types as in X.520 and X.521 and simpleauthen-
   tication with unprotected passwords in bind.The network level can be
   X.25or TCP/IP. There are test duas,duacvops, duauser, witha simple
   userinterface. Certificatesfor strong authentication are included
   to x509dua and x509duacvops.VTT X500 is realized with program
   development tools CVOPS and CASN, the code is in C-language and uses
   UNIXSystem V. The code is fairly easy to port to other operating
   systems.  VTT X500 was made for Smail e-mailproductof Nokia Data
   Systems.

COMPLETENESS

   Complete DAPand DSPof 1988X.500 Recommendations are implemented.
   There are the following omissions: multicasting is not implemented,
   strong authentication of calls to dsa (optional signing of DAP and
   DSP-calls, strong authentication in bind, security error, security
   parameters in commonarguments), T61alternative in CASE IGNORE and
   CASEEXACT STRING, Criteria-syntax, TeletexTerminalIdentifier syntax.

   3ComCorporation

LAST MODIFIED

   July, 1991

KEYWORDS

   CLNP, Commercially Available, DUA Only, Multiple Vendor Platforms, X
   Window System, X.25,3Com

ABSTRACT

   The DUA process runson 3Com's dual-stack OSI/TCP terminal server,
   scheduled tobe released in mid-June1991.  It provides Presentation
   Address resolution for names, on behalf of the VTP application: when
   the user attempts anoutgoing connection ("VTP <name>" or "connect
   <name>"), <name> gets mappedto its Presentation Address.

   The DUA process supports theAddEntry, RemoveEntry, and Search opera-
   tions.  Via a menu-driven command, the system administrator can con-
   figure any of these operations, thensend the request to theDSA.  He
   would use the AddEntry operation to enter a resourcename and its
   corresponding physical address in the DIB, the DeleteEntry operation
   to remove the name and its physical address,and theSearch operation
   (with "filter" as anoption)for a display of all registerednames
   or, given a name, a display of the name's physical address.

   Regarding unbinding from a DSA, the system administrator could use an
   UnbindDSA command orset a timer which, onceexpired, would automati-
   cally perform the unbinding. The binding toa DSA, on the other
   hand, is transparent, provided the system administrator has set a DSA
   address.  The binding is triggered by eitheran outgoing connection
   attempt or an operation request sentto the DSA.

   The schema supportedby the DUA consists of the following sequence of
   object classes: Country, Organization, OrganizationalUnit (up to 3
   levels of OrganizationalUnits are allowed), ApplicationProcess, and
   ApplicationEntity.  Their respectiveattributes are CountryName,
   OrganizationName, OrganizationUnitName, CommonName, and Presenta-
   tionAddress. The CommonNameof the ApplicationEntity is always "vt"
   for VTP and is transparent to the system administrator.

CAVEATSAND GENERAL LIMITATIONS

   Deleting an entry will fail if the DUA is interacting with a6.0
   based version of QUIPU.  This is a bug in QUIPU, andversion7.0
   release willhave itfixed.

   Adding a CountryNameis disallowed if the DUA is bound to QUIPU.
   Thisdecision was made because to add a country in QUIPU, one needs
   to bind as the manager of the DSA holding the root EDB file,and such
   information may not always be available to the system administrator.
   Also, our binding isdone transparently.

ABSTRACT

   Xdi is a Directory User Agent (DUA) for the X WindowSystem. In
   addition to providing a user-friendly interface,it supports Directory
   interactionsof different levels of complexity. Users can select dif-
   ferent window screens to browse, search and modify the Directory.
   There are two different search screens for name based searchand
   attribute based search. It is simpleto use for novice usersbut is
   alsouseful for moreadvanced users to formulate complex search
   filters.  Xdi also supports "user-friendly naming" in many cases so
   thatusers are not required to know X.500 naming format.

COMPLETENESS

   The Xdi interface does not support accesses to Delete and Add DAP
   operations as in the88 Directory Standard. Read, Search, and most
   Modify operations are fully supported. Thereare no facilities to
   modify the RDNs of entries. Strong authentication isnot implemented.

ABSTRACT

   xwp is a graphical user interface tailored specifically to provide
   easyaccess to the Directoryfor thepurposes of performing White
   Pages searches. It is currently in use as one of user interfaces
   available onwp1.psi.net andwp2.psi.net, the two service machines
   for the White Pages Pilot Project.  Implements User-FriendlyNaming
   scheme developed in IETF OSI-DS Working Group.

COMPLETENESS

   Compliant with X.500standards to the extentthat the QUIPU implemen-
   tation is.

INTEROPERABILITY

   Successfullyinteroperates with QUIPU DSAs.

CAVEATSAND GENERAL LIMITATIONS

   xwp is not ageneral-purposeDUA. Itwas designed tobe a special-
   purpose front-end for performing White Pagessearches and thus, in
   the interests of simplification, does not provide the full range of
   functionality supported by the X.500standard.

ABSTRACT

   The xwp program is asimple browser for the QUIPU/X.500 directory.
   It uses OSF/Motif and the X Window System toprovidea convenient
   userinterface.

   The user interface consists of five different top-level windows: the
   mainwindow,the search window, and three option windows.  The main
   window appears when the program is executed and all others are
   reached through its menus.  The mainwindow containsCurrentLoca-
   tion, Current Descendents, Descendent Filter, Current Information,
   and Directory Statussubwindows.  The contents of these subwindows
   showinformation about the current location of the browser in the
   directory tree.  Thesearch window contains Search Area, Search
   Filter, and Search Results subwindows.

   The mouse pointer may be used in themain window to change the
   current location of the browser in the directory tree.  We can des-
   cenddeeper into thetree byclicking the mouse whenit points to a
   member of the Current Descendents list.  Doing this "moves" the
   browser to this new (one level deeper) location in the directory
   tree.  This causes the main window to be updated as follows:(1) the
   selected descendent becomes the new Current Location, (2) its descen-
   dents are listed in Current Descendents, and(3) itscontents are
   displayed inCurrentInformation.  Any problems and messagesfrom the
   directory are displayed in the Directory Status portion of the main
   window.  To move thebrowserup the directory tree (i.e. towards the
   root), clickthe mouse pointer on one of thecomponents of the
   Current Location.  In this way it ispossible to move the browser to
   any locationabove its current position (i.e. to anyancestor) in one
   mouse click. Doing this causes the main window to be updated as dis-
   cussed above.  Due to directory-imposed limits, it may not always be
   possible to display all the descendents of the current position.  In
   suchcases (and others) it may be useful to impose afilter on the

   descendents to be listed.  To do this, position the mouse pointer in
   the Descendent Filter box and use the keyboard to type in the desired
   filter expression.  Typing <RETURN> in this box causes the Current
   Descendents list to be updated usingthe newfilter.

   xwp was developed atthe University of Wisconsin - Madison Computer
   Sciences Department.It is used in conjunction with the ECI mail user
   agent project.  xwp was written by Robert Lazarus, III.
