thank you, it helped a lot.

Note to self: never set the operating system language to Italian.

If you have the following:

Debian/GNU Linux 10 (buster)
jetty-9.4 behind apache2 reverse proxy
Shibboleth-IdP-4.2.1

and you set the default operating system to Italian, English guests will 
find their language shadowed by Italian. This is a pretty distinctive 
malfunctioning as the French and German guests are not affected.

Just switch default language in Debian to English and everything works 
as expected.
