Identity Manager uses Java Naming and Directory Interface (JNDI) over TCP/IP or SSL to communicate with the LDAP adapter.
If you are using TCP/IP, specify port 389 on the Resource Parameters page.
If you are using SSL, specify port 636.
If the value cn=Directory Manager is specified in the User DN resource parameter, then the Identity Manager administrator has the necessary permissions to manage LDAP accounts. If a different distinguished name is specified, that user must have the ability to read, write, delete, and add users.
