You can use firewalling for that and redirect all unauthorized
clients to some site or local squid which can allow/disallow certain
domains with it's ACLs. 

The unauthorized users would get handed out their own network.
The access point would need to run some scripts to open firewall for
authorized MACs and the DHCP server would put authorized users to a
different DHCP class and give them a different IP range.
You could propably query your radius server and fetch all the MACs
there and open up your firewall for those MACs only.
