LDAP is the protocol at the heart of universally interoperable directory services applications. All major directory services products-including Novell's market-leading NDS and Microsoft's soon-to-be-released Active Directory-support LDAP, as does almost every important application for locating individuals and communicating across the Internet and other networks. Analysts predict that the network directory market will emerge as one of the most important areas in the next few years, and they agree that LDAP will play a central role in all directory solutions. This volume collects the RFCs that describe formal definitions for LDAP or document its interactions with other protocols, as well as informational documents that explain how LDAP operates.
