Sudden User Authentication Rejection as a result Compatibility - error

Thanks all for your contribution. For clarity:  

All users are rejected, regardless of client platform or os.

I switched over the NAS to the secondary server when the primary server started to fail and the secondary server (which has similar configuration with one failing) is authentically users successfully. The two servers use the same server certificate.

Please find attached the debug log.

It's really weird!

Best Regards

as already emntioned, there have been windows updates that have gone out recently that have caused many a mischief. we've not been affected (probably because we have our own CA for this...) - I suspect a certificate CA update on the clients which has meant the root CA or an intermediate are no longer known or trusted correctly.  if the RADIUS server pushed out it cert and ALL the chain, then local intermediates SHOULDNT be an issue...but if the root is no longer correctly known then that would be ka-blam!

easiest way to finger this...find/identify a troublesome client, visit said machine, delete the eduroam connection profile/details and reconnect - see what it says about the RADIUS cert/trust.
