Freeradius second auth factor

[Anton Kiryushkin]

Hello.

I want to configure the second authorisation factor with EAP-type, and md5
hashed password saved in MySQL.
I found several modules and services like MultiOTP and Smsotp, but I can't
understand how to provide the SMS before the authorisation or how to ask
FreeRadius to wait for the process sends SMS?

Could you please explain this to me?
