EAP Failure Code 4

[Paul Bone]

Most of us are stupidly busy people working on multiple devices and networks who don't necessarily have the time to go through reams of documentation - hence why we might ask quick questions on mailing lists and forums to try and save time as most often someone else has already had the problem.

I believe this to be Unifi issue as it works again after a reboot, but trying to cover my bases by also asking on the Freeradius list to see if anyone else is having the issue.

My question to the list was essentially - what does the EAP Failure Code 4 usually mean? If I can't get any answers to that without sending in full debugs then it will have to wait as I do not have time currently, and of course that is my issue!

  ALL of the documentation says what to do.  When you join the mailing list, you get an email telling you what to do.

  Where else do we need to put the documentation so that people will read it?
