Getting Connection refused message when trying to get MDM tasks in UWL

Hi All,

I'm trying to get MDM tasks in UWL. But I'm NOT getting any MDM tasks.

Below is the error message in the trace file. I also noticed the userid as 'Guest' in the error trace. But I have done the usermapping for the MDM system. Then why the connection is refused.

System.err#Guest com.sap.mdm.net.ConnectionException: Could not open minimum connections.#

Please help.
