      I've setup OpenVPN to work with external RADIUS server.
      Product is IDaaS from Entrust where there is a gateway that synchronize AD users to the service. The gateway also acts as RADIUS server for OpenVPN.
      In IDaaS I can select whether the user has a soft token or just uses SMS as MFA.
      Connecting using soft token works fine, but with SMS it fails immediately and after a second or two the SMS arrives.
      Looking with tcpdump/WireShark I see that upon entering credentials an Access-Request package is sent from pfSense to the RADIUS server and an Access-Challenge is returned.
      From the authentication log I get this:

      /openvpn.auth-user.php: Error during RADIUS authentication :

      The expected behaviour should be that I was prompted to enter the SMS token in the OpenVPN client, or not?
