How does ASF relate to the Lightweight Directory Access Protocol (LDAP) and X.500?
The X.500 family of standards provide a robust series of mechanisms for management of and access to directories such as electronic mail and other addresses. The X.500 Directory Access Protocol, and its “lightweight” version for the Internet, incorporates a query service for the directory. Because the LDAP query interface can be regarded as a special case of search, one can provide a gateway for ASF using the Z39.50/GILS interface to access data from an X.500 distributed hierarchical database.
