There are two basic approaches to this:
1. Install one of the several GOOD "wireless switch" back-end boxes,
which handle the login and enforce per-user (by group or role) traffic
restrictions. Some of these offer advanced features, such as allowing
users to roam from one AP to another without re-authenticating.
2. Group access points on different VLANs, according to the rights
users need. Require some kind of login to access out of the VLAN.
This is clumsy and awkward and horrible; be aware that a few "wireless
switch" products just use the user login to group clients into VLANs,
and expect your core inter-VLAN routing access lists to do all policy
enforcement...
[I'd prefer not to name names, but watch for boxes that boast how
many VLANs they allow. Oh, and note that on some boxes, roaming *may*
require proprietary APs made by the switch manufacturer.....]
