Using LDAP
Adding, modifying and deleting records on LDAP can be done using different LDAP tools. We recommend using LDAP Administrator that can be downloaded from Softerra.
Another good free tool you can download from http://ldapadmin.sourceforge.net/download/ldapadmin.html.
All mail clients supporting LDAP allow you to search records on LDAP servers. Hardly some will help you to modify records on the server. Some mail clients have a better LDAP implementation and searching is smooth and some are cumbersome and hardly to use.
