freeradius against AD authentication not working

Running Freeradius v1.1.1 on a RHEL 4 box and trying to authenticate the
WiFi users against windows 2003 active directory using EAP-MSCHAPv2. I was
able to join the linux box to windows domain successfully and able to read
the users and groups from AD. I have configured the windows XP supplicant
with root.der certificate and EAP-MSCHAPv2. When i try to connect to access
point, it takes the local machine name default instead of asking for
username and password.

Does i missed anything ? Here is my radius log file.

bash3.0#radiusd -X -A
