The goal of this document is to provide information regarding the

availability and 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 the Directory

1. Introduction

This document catalogs currently available implementations of X.500,

including commercial products and openly available offerings. It

contains descriptions of Directory System Agents (DSA), Directory

User Agents (DUA), and DUA client applications. The latter can

include such applications as browsers, DSA management tools, or

lightweight DUAs that employ an application-level protocol to

communicate with a DUA (which then in turn communicates with a DSA)

to support user service. Section 2 of this document contains a

listing of implementations cross referenced by keyword. This list

will aid in identifying particular implementations that meet your


To compile this catalog, the DISI Working Group solicited input from

the X.500 community by surveying several Internet mailing lists,



Readers are encouraged to submit comments regarding both the form and

content of this memo. New submissions are always welcome. Please

direct input to 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. This will be deter-

mined subjectively by the DISI chairperson.

1.1 Purpose

The growth of existing X.500 pilot activities (e.g., White Pages

Pilot Project) and the advent of new pilots (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

goal of DISI is to enable the continued growth of X.500 by lowering

the lack-of-information barrier. This document takes one step toward

that goal by providing an easily accessible source of information on
