2-step auth LDAP + Proxy

27 Dec 2017

      Hi,

I have a customer running a Fortigate SSL-VPN solution authenticating users via RADIUS (PAP) towards a Gemalto SAS OTP solution. The user just use the Gemalto MobilePASS app to generate an OTP code and enters that into the password field, which works fine.

However, he now wants to first authenticate the user with username/AD-password via LDAP against their AD, and if successful, the user should be prompted for the OTP code as a second step. This is currently not possible with the Gemalto SAS solution, so I’m therefor trying to deploy a FreeRADIUS (v3.0.13 on CentOS7) server in between and have FR perform the AD auth, return an Access-Challenge and then proxy the second Access-Request with the OTP code to Gemalto RADIUS.

I’ve successfully managed to independently configure FR with the LDAP module to authenticate the username/password against their AD, or configure it as a proxy to send the requests to Gemalto, but I can’t really figure out how to chain these two auth methods together. After I enabled proxying of NULL realm, the first auth request is sent straight on to Gemalto.

Is it even possible with pure configuration, or would I have to patch the two modules to accomplish this? Any hints would be greatly appreciated.

PS: I have no need for authorizing the user AD group belongings etc in FR, this is done in the second step by Gemalto anyway. I just need pure authentication against the AD in step 1.

This is what I got so far:
