I am looking for the best EAP method to use for a diverse environment where end clients will be a mixture of Windows XP, Windows 7 and iPad devices. I would like to use one SSID and security method for all devices. Microsoft AD 2008R2 is the back end database I can authenticate to. I only want company devices to be able to authenticate.
Which EAP flavor would help in all of these criteria?
I have been looking at EAP-FAST, PEAP and EAP-TLS. Any feedback would be most appreciated.
