Hi all/anders, As told, i tried freeradius-2.1.1, but same result. Actaully my setup involves wifi client supporting PEAP ---------> EAP-MD5 |-----> EAP-Token_card l------> EAP-MSCHAPv2 Attached is debug log file. Wifi client is installed on Windows XP _Service pack 2 OS. SETUP: wifi client(WINXP) <---------> AP <-------------------> freeradius-2.1.1 server. The setup works with PEAP_EAP-Tokencard and PEAP_EAP-MSCHAPv2 But fails only for PEAP_EAP-MD5. Is it because of the supplicant (Win XP). Kindly reply. Regards Prasad
