I used an older version of xsupplicant and the last CVS version of hostap and 
it worked with the minimal authentication server of the hostap. 

But i had a problem when i used another machine for RADIUS. I enabled routing 
at the machine which was acting as an Access Point and i saw that the Access 
Point sends an EAP-Request/Identity at the supplicant, the supplicant 
responds with a EAP-Response/Identity, then the AP sends an Access-Request to 
the Radius server, the Radius responds with an Access-Challenge but the 
authenticator does not forward this message to the supplicant. Do you know 
why?

Thanks in advance
Dimitris
