First off, forgive me if this has been asked before on this list (I did do a search first, yet no results proved useful).<br><br>I am on a fact finding mission to see whether freeradius is going to be feasible to deploy in my environment (~50 users over ~40 windows and linux desktops). On a test network I have configured an Ubuntu 9.10 Server with a patched freeradius that has openssl (oh what fun that was to build).<br>
<br>I have so far altered the original configuration by only a few lines, as everywhere I go I see Alan screaming "Don't change the config!". I changed eap.conf by the following<br><br>default_eap_type = tls<br>
...<br>fragment_size = 1024<br>include_length = yes<br><br>I also changed users to include a few lines, most of which are incorrect, one of which may be correct (but I'm not sure). I added them one at a time in case one did the trick, but no such luck.<br>
<br><a href="http://example.com/user">example.com/user</a><br><a href="mailto:user@example.com">user@example.com</a><br>host/user<br>winlaptop/user<br>WinLaptop/user<br><br><br>I also edited client.conf to include my NAS (pretty standard change so I'm not going to detail it)<br>
The issue is when a windows client (A user by the name of user on a laptop named WinLaptop) attempts to connect, it cannot Authenticate. The error seems to be that the user name doesn't match between something and the TLS attrtibute. I would love more info on what this implies and how TLS and Radius work with each other.<br>
<br>I get the following radiusd -X output: (sorry for the length)<br>FreeRADIUS Version 2.1.8, for host i486-pc-linux-gnu, built on Jan 15 2010 at 23:02:23<br>Copyright (C) 1999-2009 The FreeRADIUS server project and contributors. <br>
