don't mind the misspells.
The issue is another one now...
Thanks to @abarlet at samba.org <abarlet at samba.org> I was able to find an old
21h2 windows 11 PC and add it to the domain perfectly, indeed confirming
the issue to be this one here
<https://bugzilla.samba.org/show_bug.cgi?id=15197>.
I tried to update the software but the latest version I'm able to install
is "Samba 4.15.9-Ubuntu" on "Armbian 22.08.4 Jammy with Linux
5.15.72-sunxi".
How can I upgrade to Samba 4.16, do I just have to wait for an update in
some future? Am I doomed?
