Just to follow up (in case anyone cares :-).

Andreas's issue is a problem with his system
not correctly getting all the correct groups
attached to his token when the LEVEL1+Administrator
log in, not a problem with the force user

So the patch is good as it stands.

We'll follow up on his issue separately.
