Hi
Is EAP-PEAP-GTC User-Password is set while using Free Radius as a proxy?
We have a radius server which does not understand EAP.
We want to authenticate the WiFi clients with this server.
In order to achieve this we have configured the Free Radius as proxy (EAP-PEAP-GTC).
But this does not seems to be working as at our server end we do not receive clear text password.
Here is the radiusd debug output:
