6.9     Conclusion

   Establishing a Directory service within an organization will involve
   a great deal of cooperative effort. It is essential to get commitment
   from the integral parties of an organization at the onset.  This
   includes the technical, legal, and data managements components of the
   organization.  Executive level commitment will make it much easier to
   get the cooperation necessary.

   Operational procedures must be clearly defined, as the inclusion in a
   globally distributed service has wide visibility. Adherence to these
   procedures must be maintained to the highest degree possible as
   misinformation may result in unintentional legal violations and
   unreliable access or data can adversely affect on a companys
   reputation.

   An X.500 Directory can be extremely useful for an organization if it
   operates as designed. It may serve as the "hub" of the information
   routing and the basis for several everyday activities. A successful
   service will be one of the most important tools for communication in
   the computer network environment. For people to make use of the
   service, they must be able to rely on consistent and accurate
   information.
