An LDAP Client sends a message to the LDAP Server whenever it requires information. The LDAP Server responds with either the answer to the inquiry or a link to where the answer may be found. Another LDAP server is usually the other site. The TCP/IP protocol is used to send LDAP messages, resulting in the establishment and disconnection of a session between the server and the client. The client then conducts the required function on the server data when the session has been established.
