Stripped-User-Domain case insensitive

[wouldsmina]

Hi,

I'am testing Freeradius with this guide
<https://wiki.freeradius.org/guide/eduroam>, but when I put a capital
letter in my domain name (example: anonymous at mydomain.COm), the requests
are proxied.

I think I need to add something here (into site-enabled/default) :

...
if (Stripped-User-Domain != "${operator_name}") {
...


I tested :
...

if ("%{tolower:Stripped-User-Domain}" != "${operator_name}") {
...


but it doesn't work (all requests are proxied).

what wrong?

thanks.
