What I'm basically saying is unless something has changed recently, you are
limited very much by the switches order of operations; which makes doing
what you're wanting to do something that is easier implemented on the
authentication server. In your case you're using RADIUS which is rather
limited on user level based permissions. Stepping up to something like tac+
would resolve your issues. There is freeware TACPLUS available, this isn't
something that would require say a Cisco ACS/ISE.
