2116: X.500 Implementations Catalog-96.

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.
