What is LDAP (Lightweight directory access protocol)?

Lightweight Directory Access Protocol (LDAP) operates on TCP/IP, utilized to access data from directories. It is used to maintain distributed directory information services over an Internet Protocol (IP) network. The normal utilization of LDAP is to give a focal spot to validation, which means it stores usernames and passwords. This permits a wide range of utilizations and administrations to interface with the LDAP server to approve clients. LDAP utilizes a somewhat basic, string-based query to extract data from Active Directory.
