      Hello,

      I'm trying to setup OTP authentication with FreeRadius 3 on pfSense 2.4.2. I believe everything is setup correctly but it just NEVER works. I have tried with mOTP and with Google Authenticator, making sure to append the user pin before the OTP when using Google Authenticator - it still doesn't work.

      FreeRadius is configured at least semi-correctly, because it works if I give the user a password, rather than using OTP…

      Every time I attempt a connection, I get "Connection Failed. Username or Password Incorrect" on the connecting device - though of course, they are both correct.

      Looking at the logs, I get this every time (regardless of whether I'm using mOTP or Google Authenticator):

      (18) Login incorrect (mschap: FAILED: No NT/LM-Password. Cannot perform authentication): [username] (from client [whatever] port 0 via TLS tunnel)
      (19) eap_peap: This means you need to read the PREVIOUS messages in the debug output
      (19) eap_peap: to find out the reason why the user was rejected
      (19) eap_peap: Look for "reject" or "fail". Those earlier messages will tell you
      (19) eap_peap: what went wrong, and how to fix the problem
      (19) Login incorrect (eap_peap: The users session was previously rejected: returning reject (again.)): [username] (from client [whatever] port 0 cli xx-xx-xx-xx-xx-xx)

      It's as if it doesn't get that I want to use OTP and it's looking for a password and failing because there isn't one. It seems to always think I want to use eap-peap. I don't. And my user is setup for OTP… I have not even touched the EAP page, in FreeRadius, so everything is set to the default values.

      My Radius Authentication server is set to PAP, under System / User Manager / Authentication Servers.

      I'm at a complete loss. Reinstalled pfSense from scratch - no dice, exactly the same issue...

      Any help would be very much appreciated. I'll be more than happy to provide logs / screenshots if needed.

      Cheers

        Hello,

        I'm just wondering if anyone has experienced the same issue or if anyone has some insights that could point me in the right direction (i.e. what/where I should be looking). As far as I know, there is no setting (at least in the pfSense GUI) to disable EAP.

        Any hints would be greatly appreciated.

        Cheers
