EAP-GTC & Yubikey

[cellkites at hushmail.com]

I've been attempting to integrate yubikeys with freeradius and have
had great success with the included yubikey module authenticating
against both stored aes keys and a private otp validation server.
However I am now attempting to use them in conjunction with EAP-GTC
and am slightly lost.

Under the gtc section of the eap module config i see that a user
password is returned from the connecting client and passed onto
another module for authentication. Is it possible to then pass this to
the yubikey module to extract the otp portion, authenticate the otp
and then continue with PAP authentication using the users password?

Is there another way i should be going about this?
