lightweight directory access protocol (LDAP)

Lightweight Directory Access Protocol (LDAP) is a TCP/ IP-based directory access protocol that has become a standard solution for accessing network directory services for databases, e-mail, storage areas, and other resources on the Internet and intranets. LDAP is standardized by the Internet Engineering Task Force( IETF) and provides a uniform standard for directory services( DS).

The connection-oriented LDAP protocol supports the functions required for communication between the LDAP client and the X.500 server or LDAP server. These include logging on to the server, searching for all information about a particular user, modifying data such as changing a password, and replicating data between different directories. The protocol does not define directory content or how the directory service should be provided.

Authentication and control operations include logging in, querying, and canceling the query; query operations include searching, reading, and comparing; and update operations include adding, deleting, and modifying entries. LDAP is based directly on TCP/IP and works on a client-server basis, where the X.500 user directory is involved on the server side. During communication, the LDAP client is connected to the LDAP server via TCP/IP. This can contain the directory service or be connected to an X.500 server via a gateway.

In the Lightweight Directory Access Protocol (LDAP) a part of the Directory Access Protocol( DAP) was implemented. LDAP is an Internet Engineering Task Force (IETF) standard, it has a globally unique format in which all names can be represented, it provides different layouts and a unique mapping between names and their internal representation. It is specified in RFCs 2251-2256, 2829-2830, and 3377.

In addition to the connection-oriented LDAP protocol, another lightweight protocol is the Connectionless Lightweight Directory Access Protocol( CLDAP).
