I am trying to implement a Silverlight Web Mapping application with ArcGIS server and I'm trying to use the Token authentication with active directory as the user/roles store.

I have the service running so that I can successfully obtain tokens but when I try to put them in a map service the map service fails with the 'Unauthorized Access' exception.

I have made sure that the account is in the permissions for that service.

I've been on the ESRI forms and I've found about 4 other posts with people with the same problem, but no solutions (I hate ESRI's site). 

Hopefully the stack can help.
