Abstract

   This document is a revision to [RFC 1632]: A Revised Catalog of
   Available X.500 Implementations and is based on the results of data
   collection via a WWW home page that enabled implementors to submit
   new or updated descriptions of currently available implementations of
   X.500, including commercial products and openly available offerings.
   [RFC 1632] is a revision of [RFC 1292].  We contacted each
   contributor to [RFC 1632] to request an update and published the URL
   of the WWW home page survey template in several mailing lists to
   encourage the submission of new product descriptions.

   This document contains detailed description of 31 X.500
   implementations - DSAs, DUAs, and DUA interfaces.

1.  Introduction

   This document catalogs currently available implementations of X.500,
   including commercial products and openly available offerings.  For
   the purposes of this survey, we classify X.500 products as,

      DSA

         A DSA is an OSI application process that provides the Directory
         functionality,

      DUA

         A DUA is an OSI application process that represents a user in
         accessing the Directory and uses the DAP to communicate with a
         DSA, and

      DUA Interface

         A DUA Interface is an application process that  represents a
         user in accessing the Directory using either DAP but supporting
         only a  subset of the DAP functionality or a protocol different
         from DAP to communicate with a  DSA or DUA.

   Section 2 of this document contains a listing of implementations
   cross referenced by keyword.  This list should aid in identifying
   implementations that meet your criteria.

   To compile this catalog, the IDS Working Group solicited input from
   the X.500 community by publishing a URL for a set of on-line
   description forms deployed on the WWW as a home page on an InterNIC
   server. This URL

   (http://www.internic.net/projects/x500catalog/catalogtop.html) was
   advertised on the following directory-related mailing lists:
   iso@nic.ddn.mil, isode@nic.ddn.mil, osi-ds@cs.ucl.ac.uk,
   ids@merit.edu, ietf-asid@umich.edu, mhs-ds@mercury.udev.cdc.com,
   nadf-l@ema.org, and dssig@nist.gov.

   Readers are encouraged to submit comments regarding both the forms
   and content of this memo.  New submissions are welcome.  Please
   direct input to the Integrated Directory Services (IDS) Working Group
   (ietf-ids@umich.edu) or to the authors.  IDS will produce new
   versions of this document when a significant number of substantive
   comments have been received or when significant updates and/or
   modifications to X.500-related standards documents have been
   ratified.  This will be determined by the IDS chairpersons.

1.1  Purpose

   The Internet has experienced a steady growth in X.500 piloting
   activities. This document hopes to provide an easily accessible
   source of information on X.500 implementations for those who wish to
   consider X.500 technology for deploying a Directory service.

1.2  Scope

   This document contains descriptions of both free and commercial X.500
   implementations.  It does not provide instructions on how to install,
   run, or manage these implementations.  The descriptions and indices
   are provided to make the readers aware of available options and thus
   enable more informed choices.

1.3 Disclaimer

   Implementation descriptions were written by implementors and vendors,
   and not by the editors. We worked with the description authors to
   ensure uniformity and readability, but cannot guarantee the accuracy
   or completeness of the descriptions, nor the stability of the
   implementations.

1.4  Overview

   Section 1 contains introductory information.

   Section 2 contains a list of keywords, their definitions, a cross
   reference of the X.500 implementations by these keywords and a table
   containing implementor name, implementor abreviation, and the page of
   this document on which the description begins for a particular
   implementor.

   Section 3 contains the X.500 implementation descriptions.

   Section 4 has a list of references.

   Section 6 lists the editors' addresses.

1.5  Acknowledgments

   The creation of this catalog would not have been possible without the
   efforts of the description authors and the members of the IDS Working
   Group.  Our special thanks to the editors of [RFC 1632], Linda
   Millington and Sri Sataluri who graciously contributed the nroff
   source file used to structure their version of the catalog.

2.  Keywords

   Keywords are abbreviated attributes of the X.500 implementations.
   The list of keywords defined below was derived from the
   implementation descriptions themselves.  Implementations were indexed
   by a keyword either as a result of: (1) explicit, not implied,
   reference to a particular capability in the implementation
   description text, or (2) input from the implementation description
   author(s).

2.1  Keyword Definitions

   This section contains keyword definitions.  They have been organized
   and grouped by functional category. The definitions are ordered first
   alphabetically by keyword category, and second alphabetically by
   implementation name within keyword category.

2.1.1  Availability

   Available via FTP

NAME

   Critical Angle X.500 Enabler

   (CAIx500e)

ABSTRACT

   The X.500 Enabler product allows an LDAP-only directory server to be
   integrated into X.500 environments, by transparently converting X.500
   DAP and DSP requests into LDAP requests.

   The initial release scheduled for 4Q96 will allow for connections
   from X.500-capable clients and servers to an LDAP-capable server, and
   will support the following features:

      * LDAP version 2, as defined in RFC 1777,

      * all attributes defined for LDAPv2, with the exception of
        certificates  and revocation lists,

      * X.500(1988) DAP and DSP protocols over TCP/IP (using  RFC
        1006),

      * the following operations: Bind (with  none or simple
        credentials), Read, Compare, List, Search, Abandon, AddEntry,
        ModifyEntry, RemoveEntry and ModifyRDN,

      * the X.500(1993) critical extensions field, to aid in
        deployments incorporating 1993 DSAs.

   This release will be available for Solaris 2.5 (SPARC and Intel) and
   Windows NT 4.0 Server (Intel).

   The product is expected to enter a public beta test period in
   September 1996.  Beta test evaluation copies will be free (limited to
   two copies per site) but will be set to expire in December 1996.

   Released versions of X.500 Enabler will be licensed per server, and
   will be distributed over the Internet.

COMPLIANCE with X.500-1988 (applicable only for DSAs and DUAs)

   The X.500 enabler accepts DAP and DSP connections.

   It supports Bind (with none or simple credentials), Read, Compare,
   List, Search, Abandon, AddEntry, ModifyEntry, RemoveEntry and
   ModifyRDN.



Apple & Rossen               Informational                     [Page 34]
RFC 2116            X.500 Implementations Catalog-96          April 1997


   It supports the attributes and object classes defined in X.520 and
   X.521.

COMPLIANCE with X.500-1993 (applicable only for DSAs and DUAs)

   The X.500 Enabler will accept connections from X.500(1993) DUAs and
   DSAs.

   It supports the X.511(1993) critical extension mechanism.

   Non-critical protocol fields which do not map onto LDAPv2 are
   ignored.

   Attribute and object classes from X.520(1993) and X.521(1993) are
   supported, including collective.  Operational attributes from X.501
   are supported, with the exception of subschema.

   As LDAPv3-based servers become available, it is expected that the
   X.500 Enabler will be upgraded to map more of the X.500(1993)
   protocol onto LDAPv3.

CONFORMANCE WITH PROPOSED INTERNET STANDARDS

   [RFC 1006] is the supported transport service.

   The product supports the object classes and attributes defined in RFC
   1274.

CONSISTENCE WITH INFORMATIONAL AND EXPERIMENTAL RFCs

   [No information provided. -- Ed.]

INTEROPERABILITY

   The X.500 Enabler is being tested with public-domain X.500 and LDAP
   clients and servers, and with the various X.500 clients and servers
   connected to the PARADISE project, such as from the ISODE Consortium.

   Critical Angle intends to do interoperability testing with commercial
   LDAP-only servers as they become available.

PILOT CONNECTIVITY

   This product will be used to connect LDAP-only servers, such as
   University of Michigan's slapd, and many vendor's forthcoming
   commercial LDAP server products, into the PARADISE project directory,
   so that they can be accessed by LDAP and X.500 DUAs throughout the
   project.

BUGS

   Bugs reports may be sent to <bug-x500e@critical-angle.com>.

CAVEATS AND GENERAL LIMITATIONS

   X.509 certificates and revocation lists are not supported due to
   limitations in the LDAP version 2 protocol. This restriction will be
   removed once LDAP version 3 servers become generally available.

   Under Windows NT there are limitations on the number of simultaneous
   incoming connections.

INTERNETWORKING ENVIRONMENT

   This product supports RFC 1006 for DAP and DSP, and LDAP over TCP.

HARDWARE PLATFORMS

   This product will initially be available for Sun Solaris 2.5 SPARC
   and Intel, and Windows NT Server 4.0 Intel.

   Subsequent versions may be available on additional platforms.

SOFTWARE PLATFORMS

   An LDAP-based server, such as the freely-available slapd, is
   required.  It does not need to run on the same host as the X.500
   Enabler.

NUMBER OF IMPLEMENTATIONS IN THE FIELD

   [No information provided. -- Ed.]

AVAILABILITY

   This product is licensed per-host server, and is distributed over the
   Internet.

   In addition to discounts for large deployment orders, subscription
   programs permit customers to obtain subsequent update releases at a
   substantial discount.

   Beta test evaluations are free (limited to two copies per site), and
   will expire 90 days after the start of the beta period.

ABSTRACT

   The CXDUA is a Windows 3.1 DUA that has been derrived from a highly
   portable and flexible Unix based Administrative Directory User Agent.
   The goal of the original design was to support features to assist a
   directory administrator in managing the directory.  These features
   include a highly portable GUI, Entry Templates, Entry Lists, Batch
   Operations and Directory Control Functions.

   Both the Windows and the Unix versions support strong authentication.

   The Unix DUA has been used in various DMS and NSA pilot projects.

ABSTRACT

   DC X500 provides a truly scalable X.500 based enterprise directory
   server with the necessary architectural flexibility to enable
   integration with existing database and directory technologies.

   From a pure X.500 standpoint, DC X500 provides a full function
   state-of-the-art DSA implementation.

      * Architected from scratch according to the 1993 X.500
        standards (i.e. not a 1988 DSA with 1993 features grafted on)

      * Support for all the key X.500 OSI protocols:

         * Directory Access Protocol (DAP) for user access

         * Directory System Protocol (DSP) for distributed DSA
           comunications

         * Directory Information Shadowing Protocol (DISP) to support
           replication between servers to give improved performance
           in a distributed network

      * Support of the 1993 Basic Access Control and  Simplified
        Access Control models

      * Support for the key Internet  X.500 related standards:

         * integrated Lightweight DAP (LDAP)for DUA access

         * Madman MIBs for easy integration with SNMP

   The DC X500 architecture is based on Data Connection's underlying
   product architecture which has evolved since 1987 and includes:

         * genuine multi-threaded implementation

RFC 2116            X.500 Implementations Catalog-96          April 1997


         * true  portability (the product is available on a range of
           operating systems e.g Windows NT, AIX, HP-UX. OS/2 etc and it
           is possible to port the core  technology to any
           hardware/software platform)

         * secure service recording for operation tracking and billing

         * support for system monitoring (both alarms and statistics)

   Key product features include:

         * Name resolution and integrated use of Search Indices based on
           2-3 trees leads to high performance operation evaluation
           (subsecond response times on  million entry DSAs)

         * Generic schema support based on 1993 concepts that allows
           customers to tailor the schema to meet their precise data
           structuing requirements

         * System recycle time is minimised (e.g. DC X500 can be backed
           up while running and  search indices are dynamically updated),
           helping achieve the goal of continuous (24x7) availability
           and high reliability.

         * No artificial software constraints are imposed resulting in a
           truly scalable product - assuming the availability of the
           necessary hardware DC X500 can be configured  to support
           millions of entries in a single DSA.

   DC X500 is certified for used within the Paradise Pilot project.  The
   product has also undergone interoperability testing at the EuroSInet
   interoperability workshops in Europe.

NAME

   DE

ABSTRACT

   DE (Directory Enquiries) is intended to be a simple-to-use DUA
   interface, suitable for the naive user, and suitable for running as a
   public access dua.  it will work on any terminal.  The user is
   presented with a series of (verbose) prompts asking for person's name
   department organization  country.  There is extensive on-line help.
   The matching algorithms are such that near matches are presented to
   the user before less good matches.

   There have been a few minor enhancements since the description in
   [RFC 1632].  The power searching feature still sets DE apart from
   most other DUAs - this allows a user to search for an entry even when
   they do not know the name of the organisation in which the person
   works - you still have to specify the country.  DE also allows UFN
   style searching.  DE uses slightly different search algorithms
   depending on whether it is accessing part of the Directory mastered
   by a Quipu DSA - Quipu DSAs tend to use lots of replication and so
   encourage searching.  DE incorporates a QOS feature where it
   maintains a database of past information availability and DSA
   responsiveness.  Translations exist into at least 4 different
   languages.

   DE runs over ISODE DAP and University of Michigan LDAP.  There is a
   version of DE, called DOS-DE, which has been ported to DOS, and this
   uses LDAP.

   DE was funded by the COSINE PARADISE project, and DE is used as the
   PARADISE public access dua. You can test the software by telnet to
   directory.ja.net and logging in as dua -- no password required.

   DE tries to cater well for the general case, at the expense of not

NAME

   Digital X.500 Directory Server Digital Equipment Corporation

   This single entry covers a number of different products

ABSTRACT

   The Digital X.500 Directory Services product set includes a directory
   server product and a variety directory user agents, as well as a
   directory synchronizer utility.

   The Digital X.500 Directory Server product provides a high
   performance DSA implemented according to the 1993 edition of the
   standard. The InfoBroker Server product extends this to provide the
   server component for LDAP and WWW user agents.  Features of these
   servers include:

         * Integrated multi-protocol support allowing concurrent DAP,
           DSP, DISP and DOP access over OSI and TCP/IP (using [RFC
           1006]) protocols.

         * Indexed database (DIB) to support high-performance searching
           and sophisticated matching including approximate match.

         * A DIB based on the 1993 edition Extended Information Models.

         * Support for chaining and referrals in support of a
           distributed DIB

         * Support for the 1993 edition Basic Access Control scheme.

         * Configurable schema based on the 1993 edition (including
           attributes, object classes, structure rules, name forms).

         * Support for 1993 edition Shadowing using the DISP and DOP
           protocol, including both incremental and on-change features
           for high performance.

         * Remote management to control DSAs and log significant events.

         * Support for the LDAP protocols using the InfoBroker Server
           product across either TCP/IP  or DECnet transport protocols.

         * A Look-up Daemon that accepts requests from Web Browsers,
           allowing access to the directory from any web browser.

         * Both X/OPEN XDS/XOM and LDAP APIs.

         * An award winning documentation set.

   The Digital X.500 Administration Facility, X.500 Information Manager
   and InfoBroker Client products provide MS-Windows, Motif and command
   line interfaces to access and manage the information stored in the
   X.500 directory, including:

         * Support for different ways of accessing the directory, either
           by browsing or searching based on an  extensible set of
           filters.

         * Support for bulk load, unload and reload of entries.

         * Driven off the same configurable schema information as the
           DSA allowing extensibility of window layouts and text to
           support customer-defined object classes and attributes.

   The Synchronizer-500 is an X.500 DUA which:

   * Enables bi-directional synchronization between X.500 and
     virtually ANY other non-X.500 directory facilitating common
     management.

   * Maps incoming data into X.500 using flexible configuration
     files

   * Facilitates creation of a multivendor electronic mail
     database, creating addresses in the appropriate syntax for
     any mail system.

   * Provides uniqueness checking on mnemonic O/R addresses,
     preventing address duplication

COMPLIANCE with X.500-1988 (applicable only for DSAs and DUAs)

   The Digital X.500 Directory Services products are based on the 1993
   edition standard. They are compatible with, and interwork with, 1988
   edition DUAs and DSAs, and are implemented to conform to relevant
   NIST OIW and EWOS agreements and the X.500 Implementors Guide.

   OSTC conformance testing (1988 DUA/DAP, DSA/DAP) has been completed
   and registered successfully.

NAME

   DIR.X (tm) V3.1 Siemens Nixdorf Informationssysteme AG

ABSTRACT

   DIR.X V3.1 is Siemens Nixdorf's Directory Service product compliant
   with the 1988 ITU-T X.500 recommendations. Siemens Nixdorf has
   supplied its Directory Service product as the GDS (Global Directory
   Service) component to OSF DCE.  However, DIR.X V3.1 has a number of
   features and enhancements which are not available in the GDS
   component of OSF DCE.

   DIR.X V3.1 is a distributed, replicated Directory Service. It
   consists of DSA, DUA and a tools package including comfortable
   administration and management utilities. DIR.X implements the
   protocol stack ranging from LDAP, DAP, DSP over ACSE, ROSE,
   Presentation, Session down to [RFC 1006]. On transport layer it
   supports TCP/IP and OSI LAN/WAN protocols.

   Data stored by DIR.X can be accessed via

      * the MS-Windows user interfaces DIR.D/ORG.D which are
        available as separate products from Siemens Nixdorf

      * any third-party LDAP or DAP browser

      * directory applications using the standardized X/Open XDS/XOM
        APIs (Directory Service / OSI Abstract Data Manipulation).
        The Siemens Nixdorf implementation was the first to gain
        XPG4-certification.

      * a command-line administration program

      * a menu-driven administration  program

      * WWW

      * a shell interface

      * the Query-by-mail interface of SNI's directory
        synchronization product DIR.X-SYNC

   DIR.X enables

      * The storage of globally-unique, tree-like name structures
        which can be mapped onto organizations.

      * The use of several alternative names (aliases) for one and
        the same directory entry.

      * Search queries that allow the user to select objects on the
        basis of specific attributes and their values, as with a
        "Yellow Pages" telephone directory

      * Treemanagement functions which can cover entire subtrees.

      * The creation and automatic updating of copies ("shadows")
        from remote computers.

      * Access protection at attribute level, which regulates access
        on an object-specific basis.

      * The storage of unstructured attributes (graphics, pixels).

   The tools package of DIR.X V3.1 includes:

      * gdssetup: A simple-to-use tool for the generation and
        initialization of a directory configuration.

      * gdshdsch: Enables the directory administrator to modify the
        directory schema off-line.

      * X.500 MIB access via SNMP

      * gdscp: A TCL based administration tool for UNIX clients with
        full XDS functionality

NAME

   DIR.X (tm) V4.0 Siemens Nixdorf Informationssysteme AG

ABSTRACT

   DIR.X V4.0 is Siemens Nixdorf's Directory Service product compliant
   with the 1993 ITU-T X.500 recommendations. The implementation
   incorporates SNI's experience of 10 years development, support and
   maintenance of the DIR.X products conformant to the 1988 Directory
   Standards, and has the following main features:

      * It conforms to the 1993 Directory standards, with particular
        emphasis on the requirements for interoperability with other
        X.500 implementations

      * The implementation is scaleable: it handles small-scale
        workgroup directories as well as very large directories for
        backbone solutions in large organisations

      * The implementation is extensible: new functionality can
        easily be incorporated

      * Existing databases and proprietary directory services can be
        accessed or integrated with the implementation.

      * Particular emphasis is placed on ease of administration of
        the Directory Service a service based on DIR.X V4.0 can be
        administered effectively from a central site, including the
        management of configuration and monitoring options

      * The implementation has a high throughput performing well not
        only on small systems, but also on high-performance backend
        servers, handling hundreds of requests in parallel on a
        multiprocessor machine.

   DIR.X V4.0 is a distributed, replicated Directory Service. It
   consists of:

      * DSA

      * DUA

      * Command-line DUA using a TCL (Tool Control Language) shell
        interface (dirxcp)

      * Management centre (dirxadm)
