The ldap realm allows you to use an LDAP database for user security information. An LDAP directory service is a collection of attributes with unique identifiers. The ldap realm is ideal for deployment to production systems.
In order to authenticate users against the ldap realm, you must create the desired user(s) in your LDAP directory. You can do this from the Administration Server’s Users & Groups tab or from your LDAP directory product’s user management console.
