We have around 15 Airport Extremes, a couple of xserves, and an active directory. The Airport Extremes currently use MAC Address filtering for keeping public users off. It’s becoming a pain in the butt to continually update all of their MAC address lists. At an Apple event I went to one of the Mac guys recommended that we use the radius server that is already built into Active Directory. Now my question is has anyone done this yet? Or should I just put Open Radius on my xserve? Any comments or suggestions would be appreciated.
