Tryign to Setup RADIUS Authentication

I was not able to do a succesful test but I decided to save the configurations anyways.

I am seeing the following in the logs:

Any ideas on what might be going on? Oh, sniffing on the line I can see the Access-Request going out, but it is receiving an Access-Reject. Testing with radclient produces the Access-Request/Access-Accept.
