                  A Survey of Advanced Usages of X.500

Abstract

   This document is the result of a survey asking people to detail their
   advanced usages of X.500. It is intended to show how various
   organizations are using X.500 in ways which extend the view of X.500
   as a "White Pages" service.  This RFC is a product of the Integrated
   Directory Services Working Group of the Application and User Services
   Areas of the IETF.

1. Introduction

   As the use of X.500 spreads in the Internet, organizations are
   finding uses for it which go beyond the "white pages" paradigm which
   has been used to introduce it to new users. Consequently, to document
   those new uses and to encourage the wider use of X.500, we sent out a
   survey to obtain "advanced usages" of X.500.

1.1 The survey

   The survey we sent out is included here for two purposes:

   1) completeness, and
   2) we'd like to encourage anyone who retrieves this document to send
      us their advanced usage for inclusion in the next revision.

   If you wish to fill this out, please send it to the working group
   list: IDS@merit.edu.

1.2 Disclaimer

   Descriptions of the advanced usages were written by the implementors,
   and not by the members of IDS. Although IDS has worked with the
   description authors to ensure readability, no guarantees can be made
   regarding the validity of descriptions. Caveat emptor.
