3. Lightweight Directory Access Protocol
The Lightweight Directory Access Protocol (LDAP; /ˈɛldæp/) is an application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network.

4. Lightweight Directory Access Protocol - History
X.500 directory services were traditionally accessed via the X.500 Directory Access Protocol (DAP), which required the Open Systems Interconnection (OSI) protocol stack. LDAP was originally intended to be a lightweight alternative protocol for accessing X.500 directory services through the simpler (and now widespread) TCP/IP protocol stack. This model of directory access was borrowed from the DIXIE and Directory Assistance Service protocols.
