WYSE device manager access

WYSE device manager access

I just got a wyse environment to support and when I try to run the WDM from the rapport server I get the message that I don't have permissions to the DB. I ran the MDTools utility and it shows no users. I tried to do a "run as" on the WDM with the local rapport user and default password with no luck. the version of WDM is 4.5.3. Yeah, I know it's old and not supported but I just got this and thinking I need to see what I have before changing much. Any thoughts on what I can do to get access?
