What you are talking about requires very specialized wifi setups, which AFAIK no freely-available tools implement. You need to be talking to enterprise wifi hardware vendors to get that kind of thing. RADIUS is an AAA (Authentication, Authorization, and Accounting) protocol. It might be one small tool used in authorization, like letting employees on the network, but that would be up to the wifi vendor's controller system (some can use RADIUS, some can use AD, some use their own systems, etc.). -- Chris Adams <linux at cmadams.net>
