I have a wirless network using Controller on some sites and AP autonomous on others. Im using EAP leap and FAST with wpa(tkip). and I have ACS. soo the problem is that using CSSC with eap-fast is Authent fail on Autonomos. leap work fine. and on light aps work fine. I probe another client on laptop(Dell wireless WLAN card utility) and eap-fast work fine on AP-autonomos and light.
