can EAP-PEAP-GTC use email pop3 server to authenticate?

[d tbsky]

hi:

     I am sorry I have a related question about "EAP-PEAP-GTC". my
script which do authenticate will receive %RAD_REQUEST attribute like
below:

          'User-Name' => 'xxxx',
          'User-Password' => 'xxxx',
          'EAP-Message' => 'xxxxxxxxx',
          'EAP-Type' => 'GTC',
          'State' => 'xxxxxxxxxxxx',
          'FreeRADIUS-Proxied-To' => '127.0.0.1'

    I want to pass the attribute "Calling-Station-Id" which send by
NAS to %RAD_REQUEST.  but don't know how to do it. any configuration
file I can focus on it?
    thank again for kindly help!

Regards,
