RADIUS is a backend component of 802.1x and WPA2 Enterprise.  You appear 
to be looking for information on how to use those two.  If you look for 
documentation on those, you should be able to find what you're looking for.

You probably want to capture the WAP logs.  Their location will be best 
correlated with the specific WAP they connect to, assuming you have 
multiple.  The client MAC address will be your best indication of 
whether or not they've been there before.
