EAP-TLS

Hi,

 I have a setup where my client is trying to perform authentication to
server by using
EAP-TLS. The server is a pass through server, which forwards the packet to
the free radius.
 The free radius, instead of sending the server certificates, bails out on
seeing the client Hello and the TLS handshake aborts.

I am not being able to figure out the exact cause. Any help will be
appreciated.
