CCM fails after upgrade to 4.0

I had a similar problem. Unfortunatly I do not exacly remember and didn't take any notes.

But in my case, CCM was not able to synch the users from JTS into CCM. The problem was something with the group membership or with the licensing of the account which is doing this synch or of the admin account which run the setup.

Sorry I do nor remember better, but maybe it gives you an idea.

Thanks! The issue was the WAS cache. After clearing the cache it worked like a charm!
