How to remove unused Active Directory servers from RHEV Manager?

Issue

• RHEV Manager (RHEV-M) server is located in a DMZ which only has access to specific AD servers. The DMZ has been added to an AD site that should only access the specific AD servers mentioned before, but RHEV-M does not honour this, and randomly queries all AD servers (which it does not have access to). This creates random time outs and errors while user login.
