get upn from winbindd

[Усольцев Пётр]

Hi!
I want to receive upn in winbindd, but I don't know how to do it correctly…
*  The first option is to make edits to the SAMR protocol. It works, but it breaks the protocol itself.(samba_fix_1_samr.patch)
*  the second option is to receive upn via a direct ldap request. It only works on samba DC, where there is a sam.ldb database. Winbind does not work on clients (samba_fix_2_only_winbind.patch)
I made patches for the commit a814f5d90a3fb85a94c9516dba224037e8fd76f1(Stefan Metzmacher Feb 17, 2025) on master branch.
 
My config  /etc/nsswitch.conf:
passwd:     files winbind systemd
shadow:     tcb files winbind
group:      files winbind systemd role
 
Test:
id   user1 at test.abc
