Can you verify that you have the LDAP configuration in MB Enterprise Manager correct?
Are you able to use the LDAP credentials to log in to MB?
This works I'm able to use LDAP credentials to log in to MB.
However, I'm able to login as tcc\jsmith web client, but I want set permissions for tcc\jsmith which at the moment is not possible because I don't find LDAP users within MB Enterprise Manager.
