Hi guys,
i'm trying to setup FreeRADIUS Version 3.0.13 with multiotp BUT I want
to enter the information like this:
"{Username}:{OTP-PIN}" ==> f.e. "dani:955825" (username in users
file)
"{Password}" ==> f.e. "blabla" (password in users
file)
I think this could be a way, to get some devices to work with 2 factor,
which are not build for it.
I successfully get an ok from multiotp, by regex'ing "{OTP-PIN}"
from "{Username}:{OTP-PIN}",
but PAP is failing, because I can't get PAP to look for "{Username}"
(f.e. "dani").
It always tries to look for "{Username}:{OTP-PIN}" (f.e. "dani:955825")
in the authentication-section.
It would be nice if you could point me in the right direction.
My apologies, if this question was already asked, and I didn't find it.
Best regards
Gerald

------------
I successfully did it with
"{Username} " ==> f.e. "dani" (username in users file)
"{Password}{OTP-PIN}" ==> f.e. "blabla955825" (password in users
file)
.
But I think the
"{Username}"
"{Password}{OTP-PIN}"
way, fails when it comes to MSCHAP (with ActiveDirectory), because
Freeradius compares only password hashes and not plaintext, so it can't
recongnise what's the OTP-PIN and what's the password.
