Interesting. I am using FreeRADIUS 3.0.4 on CentOS 7 and it's still in
the manual page. Should there be an error message if it doesn't work?
And why is it working with =~ then?

I am using regexes a lot in my users file. What would be the indented
way to do the same without regexes? I currently use regexes to check the
realm if it is my own "Realm =~ example.com|NULL" and also to check for
the SSID to which a user connects to on my wifi: e.g.,
"Called-Station-Id =~ "[-A-Fa-f0-9]+:eduroam$" as the controller puts
the MAC address of the access point before the SSID.

So how do I check that instead now without regexes in the users file?

Thanks,

Gerald
