Hello, While my eventual goal is GTC + PAM, I'm struggling to get the innner-tunnel request to successfully authenticate my user through PAM. I've made the following configuration changes from a clean installation of 2.1.12 on a Gentoo Linux system: 1. Added wap to the clients file 2. Put certs in eap.conf file 3. Uncommented pam in the sites-available/default file 4. changed copy_request_to_tunnel to yes 5. Uncommented Pam in sites-available/innner-tunnel In order to test the inner-tunnel configuration I used the following command: radtest markg goodpass 127.0.0.1:18120 0 testing123 The radiusd -X output is: FreeRADIUS Version 2.1.12, for host x86_64-pc-linux-gnu, built on Feb 11 2012 at 09:59:42 Copyright (C) 1999-2009 The FreeRADIUS server project and contributors.

I'd be grateful for any assistance as to what changes I need to make so that the inner-tunnel request from rad-test would successfully authenticate via PAM. Thanks in advance for your help! Mark
