A Revised Catalog of Available X.500 Implementations

Status of this Memo

This memo provides information for the Internet community. This memo
does not specify an Internet standard of any kind. Distribution of
this memo is unlimited.

Abstract

This document is the result of a survey that gathered new or updated
descriptions of currently available implementations of X.500,
including commercial products and openly available offerings. This
document is a revision of RFC1292. We contacted each contributor in
RFC1292 and requested an update and published the survey template in
several mailing lists and obtained new product descriptions.

This document contains detailed description of twenty six (26) 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 surveying several Internet mailing lists,
including: iso@nic.ddn.mil, isode@nic.ddn.mil, osi-ds@cs.ucl.ac.uk,
and ietf-ids@umich.edu. We also contacted many people by telephone
and sent the template to several individuals and mailed a floppy disk
containing the survey template to a person who did not have Internet
access.

Readers are encouraged to submit comments regarding both the form 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 editors. IDS will produce new ver-
sions of this document when a sufficient number of changes have been
received. 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 can not guarantee the accuracy
or completeness of the descriptions, or the stability of the
implementations.

1.4 Overview

Section 1 contains introductory information.

Section 2 contains a list of keywords, their definitions, and a cross
reference of the X.500 implementations by these keywords.

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 RFC1292, Ruth Lang and
Russ Wright who helped us get started and made key suggestions that
enabled us to learn from their experience. We also acknowledge and
appreciate the efforts of Ken Rossen in obtaining six descriptions.

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
Implementation is available using FTP.

Commercially Available
This implementation can be purchased.

Free
Available at no charge, although other restrictions may apply.

Limited Availability
Need to contact provider for terms and conditions of
distribution.

Source
Source code is available, potentially at an additional cost.

2.1.2 Conformance with Proposed Internet Standards

These RFCs specify standards track protocols for the Internet
community. Implementations which conform to these evolving proposed
standards have a higher probability of interoperating with other
implementations deployed on the Internet.

RFC-1274

COSINE and Internet X.500 Schema, University College, London,
England, November 1991.

Distributed Operations extensions to provide an Internet
Directory using X.500, University College, London, England,
November 1991.

Implementation supports RFC1487: Yeong, W., T. Howes, and S.
Kille, X.500 Lightweight Directory Access Protocol, July 1993.

2.1.3 Consistence with Informational and Experimental Internet RFCs

These RFCs provide information to the Internet community and are not
Internet standards. Compliance with these RFCs is not necessary for
interoperability but may enhance functionality.

2.2 Implementations Indexed by Keyword

This section contains an index of implementations by keyword. You
can use this list to identify particular implementations that meet
your chosen criteria.

The index is organized as follows: keywords appear in alphabetical
order; implementations characterized by that keyword are listed
alphabetically as well. Note that a "*" is used to indicate that the
particular implementation, or feature of the implementation, may not
be available at this time.

For formatting purposes, we have used the following abbreviations for
implementation names: BULL S.A. (Bull X500-DS and X500-DUA), DEC
X.500 DSA (DEC X.500 Directory Server), DEC X.500 Admin (DEC X.500
Administration Facility), HP X.500 DD (HP X.500 Distributed
Directory), LDAP (University of Michigan LDAP Implementation), OSI
Access & Dir (OSI Access and Directory), and Traxis (Traxis
Enterprise Directory).
