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

Top      ToC       Page 3 
   (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.

NAME

   A-Window-To-Directory (AWTD)

ABSTRACT

   A-Window-To-Directory is a simple-to-use DUA interface available on
   PC that provides access to the X.500 Directory Services. The
   available operations are: bind (authenticated or anonymous), read,
   list, compare, modify, modifyRDN, search, add, remove and unbind.  It
   is designed to be used with the Bull X500-DUA product and for that
   reason is able to handle any of the defined schema. The new acronyms,
   objects and attributes are automatically loaded without any
   customisation.  The interface of the application may be personalized
   in several ways, through Local Preferences stored on the PC and
   through User Settings stored on the UNIX machine that runs the Bull
   X500-DUA product.

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.
