This isn't new with 22.7. I had the same issue on 22.1 as well. If I add a FreeRADIUS user via the WebUI and click apply the user never appears in "/usr/local/etc/raddb/users" (restarting the service doesn't help any either).
If I run "configctl template reload OPNsense/Freeradius" the user gets added.
Any ideas where to look to see why the apply button isn't adding users to FreeRADIUS?
When I hit apply, I can see that reconfigure is being called and returning {"status": "ok"}.
I ran "configctl template cleanup OPNsense/Freeradius" followed by "configctl template reload OPNsense/Freeradius" and things seem to be working now. :shrug:
