What we want to do is EAP-CTG, I'll investigate further in that direction. Please just let me know if for some reason freeradius doesn't support that.

Ultimately we would like to prompt the user (after successfull authentication) with a challenge that he would have to enter in a securID like device and enter his response in the mod_auth_radius prompt. I've been toying with freeradius and mod_auth_radius for a few days now, and I still haven't succeeded in prompting the user with a challenge from the RADIUS server. Could anyone point me in the right direction ? Is it possible ? We're using mod_auth_radius as a basic client, but we could use any type of NAS.
