MAC only authentication issues

20 Jul 2022

      Hello,

I've been banging my head against the wall for a couple of weeks now.
My goal is to have a freeradius server with MAC only authentication
setup on my Unifi Dream Machine. I've found various sites around the
web with smattering amounts of information, as well as some old posts
on this mailing list, but I can't seem to get it working just right.
I've tried to keep it as "vanilla" as possible to get it working
before worrying about VLAN management by MAC, so this is purely to get
something connected. I've tried adding the MAC to the "user" file per
some sites, put in the clear-text password without dashes, and a bunch
of other configurations at various points before blowing it all away
to start again multiple times. Here is my debug output:

As you can see, it looks like it accepts the MAC address. However, on
my laptop it pops up asking for username and password credentials,
regardless if I have anything in the "users" file or not (the only
difference being an extra line about a matched entry in files and
[files] = ok). Any help or next steps would be greatly appreciated.

Thanks,
