Hello Rod,

I think the A-C is supported with EAP type authentication? not the PAP.

it is supported with both types. However in EAP it is used for something entirely different. With PAP it is used with a challenge. Maybe this thread brings you up to speed. But please use the rlm_perl implementation I send you and _not_ the smsotpd because the perl implementation is much easier to setup, more reliable, less complexity and less moving parts. http://thread.gmane.org/gmane.comp.dial-up.freeradius.user/86365 Cheers, Thomas
