pfSense

hello,
the remote authentication seems to be broken.
I configured my company Cisco ACS as authentication server (type radius)
and my radius user as a member of admin group with "WebCfg - All pages" priviliges.
Anyway when i try to login the prompt says
"No page assigned to this user! Click here to logout."
but on the system logs i have a successful login event
also the authentication test (pfsense diagnostic) with the same user is successful.
Regards
