The Lightweight Directory Access Protocol (LDAP) is an application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network.
Directory services may provide any organized set of records, often with a hierarchical structure such as a corporate email or telephone directory. LDAP is an IETF standard and the latest specification is Version 3, published as RFC 4511.
