Debug output like this usually points to non-matching RADIUS secrets. Check the radius secret in your switch config as well as the secret configured in your nas SQL table. Freeradius only reads the nas table on startup, so if you make changes to that table, you must restart the daemon for those changes to take effect. Kevin Bonner Kevin, Thanks for the prompt reply. I went ahead and went to failing switches, cleared the radius-server entries and started from scratch. I had done this before, and it didn't fix the problem. But this time everything is working. It surprises me that the debug output doesn't appear to mention the failure of the NAS secret. I would have thought I would have gotten then that message and that the auth would have stopped there.
