If multiple Content Servers are running against a particular repository, you must perform some additional steps to enable LDAP authentication regardless of the particular Content Server to which a user connects.
To enable LDAP authentication with multiple Content Servers:
Using Documentum Administrator, connect to one of the nonprimary Content Servers.
Navigate to the existing ldap configuration object.
Re-enter the Binding Name and Binding Password for the LDAP directory server.
Save the ldap configuration object.
Perform steps 1 to 4 for each nonprimary Content Server.
