Thanks for the reply Jouni,

               oops...i meant to say hostapd  and not hostap in my original
mail :(
I am using madwifi driver and hostapd to set up an Access Point and
i am using wpa_supplicant and madwifi for the STA.

 I am experimenting with some EAP methods. I was wondering if it was
possible
to make hostapd authenticate the STA using EAP-TLS (or any other EAP method
for that matter)  however not encrypt the subsequent data exchanges after
successful authentication (i.e. not engage in 4-way hanshake etc.) It should
be theoretically
possible as authentication and confidentiality are two seperate security
functions.

I am bit lost as to is it as easy as changing particular config files
(hostapd/wpa_supplicant)
or would it need some code modifications ?

Thanks again for your reply

Regards
Rupinder
