             Building an X.500 Directory Service in the US

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.


   This document provides definition and recommends considerations that
   must be undertaken to operate a X.500 Directory Service in the United
   States.  This project is the work performed for the Integrated
   Directory Services Working Group within the Internet Engineering Task
   Force, for establishing an electronic White Pages Directory Service
   within an organization in the US and for connecting it to a wide-area
   Directory infrastructure.

   Establishing a successful White Pages Directory Service within an
   organization requires a collaborative effort between the technical,
   legal and data management components of an organization. It also
   helps if there is a strong commitment from the higher management to
   participate in a wide-area Directory Service.

   The recommendations presented in the document are the result of
   experience from participating in the Internet White Pages project.
