I have now implemented the needed EAPOL state machines for the .1X Authenticator in hostapd (few bugs were just fixed in CVS) and I did some testing with WinXP as the Supplicant and FreeRADIUS as the Authentication Server.

EAP/MD5-Challenge seems to work fine both with FreeRADIUS and the minimal test auth. server included in hostapd. I was able to configure the user identification and password for FreeRADIUS and use the same info on WinXP Supplicant to get the port authorized.

I'm not very familiar with WinXP certificate configuration and EAP/TLS seemed to miss something in the client side. I was able to add the trusted root certificate and a client certificate, but WinXP did not seem to find them when Supplicant needed certificates. Anyway, since the authenticator PAE and backend authentication state machines are now fully implemented, I would assume that also EAP/TLS would work with WinXP--assuming one were able to add suitable certificates for it.
