Unable to create or edit a connector.  When you try to select a Datacenter on a new Connector, or when the page attempts to render an existing Connector, you get this error:

Log into Enterprise Layer Manager (ELM) with Local Administrator account, rather than AD account. 

Problem Cause

This is a problem where long-running Active Directory queries inside the ELM create a database lock that causes the rest of the connector transaction to timeout.  It might be related to a slow-responding AD. Some improvements came in version 4.3, but some issues still remain.
