Any One-Time password system.

Hello Sergii,
don't use the C daemon it has to many moving parts. I later wrote a perl
module which is easy to use.

See:

Follow the instructions in smsotpd.2012-10-05/rlm_perl/README

If you have any further questions, let me know, but this should get you
started quick. To my knowledge freeradius 3.0 does now everything to do
smsotp natively, but I never took the time to try it. The above solution
is running in production for 3000 users.

In the tar ball is also a smsotp test client.

Cheers,
        Thomas
