Giving up for today trying to get #8021x (via ethernet, only using credentials, no certificates) working on #NixOS using #wpa_suplicant and #NetworkManager authing against a #UniFi infrastructure...
The debug output from both, NetworkManager, and (especially) wpa_supplicant is quite useless in this regard, as it focuses on technical mumble-jumble that might be useful to someone knees-deep into #RADIUS, but helps zero when it comes to a regular admin trying to get this working.
