Lightweight Directory Access Protocol (LDAP) is used to access centrally stored information over a network. LDAP servers store information in a database called a directory, which is optimized for searches. Directory entries are arranged in a hierarchical tree-like structure. This directory can store a variety of information such as names, addresses, phone numbers, network services, printers, and other types of data. LDAP can also be used to authenticate users, allowing users to access their accounts from any machine on the LDAP network.

 

RedHat Linux includes OpenLDAP, which is an open source implementation of the LDAP protocols. Below is a list of OpenLDAP Server and Client Utilities list and their respective functions.
