Hi all,

I’m using freeradius for custom 2-factor OTP authentication as below:

RADIUS_CLIENT > Access-Request(User/Pass) > FreeRADIUS(check user pass and if ok -> generates state) > Access-Challenge > RADIUS_CLIENT> Access-Request(User/OTP/state) > FreeRADIUS

In first Access-Request (before Access-Challenge) RADIUS_CLIENT is sending all required attributes well

My problem is on the second Access-Request (after Access-Challenge). There is no “Calling-Station-Id” attribute on this state for some reason…

I have checked this on the following radius client: pam_radius-1.3.17-2.el6.x86_64 (CentOS release 6.5)

Anyone can suggest some work around for above? Maybe it is configuration issue I’m missing?

Thanks a lot,

Dmitry!
