Lightweight Directory Access Protocol (LDAP)

Lightweight Directory Access Protocol (LDAP)

In large networks, most administrators have set up some kind of directory that keeps track of users and resources (e.g., NDS, Active Directory). In order to have a standard method of accessing
directories, the Lightweight Directory Access Protocol (LDAP) was developed. It allows clients to perform object lookups with a directory using a standard method. LDAP was originally
specified as RFCs 1487 (version 1) and 1777 (version 2), with RFC 3377 proposing the more commonly used third version, which fixes a number of shortcomings in the protocol.
