I am running NTLM_AUTH for mschap authentication with an MS AD at the back end. I suppose that could be the culprit. If so, is upgrading FreeRadius likely to resolve that (not knowing exactly what the problem is). Anything I could configure at the FreeRadius end to make that work a bit better? -Mike On Wed, 15 Sep 2010, Alan Buxey wrote:

Our students have returned this week, and I've noticed a couple new messages logged to my FreeRadius 2.1.3 server. When it happens, my controllers fail over to the secondary Radius server. This has happened a few times. My Radius servers are only lightly loaded, and only configured to do authentication. No databases. Any idea what might be causing this?
