LDAP (Lightweight Directory Access Protocol) is a protocol. The protocol is used for applications to connect to the directory service. The directory service contains information about users identified by their account names. The computer center of the TUHH provides the service of the central LDAP-Server 'ldap.rz.tu-harburg.de'.

Instructions: Using LDAP as addressbook

Users can change part of their user data presented by the LDAP Server.
