many thanks, got all the bits I needed 

One question though, 

Why auth and not post-auth? I'm working on the basis that the stuff I do doesn't have anything to do with the actual auth process, in post-auth I'm doing things like setting session-timeouts. vlan assignments  etc. based upon whether it's an access-request or an access-reject.

Is there something wrong with that logic?
