Winbind. dcesrv_samr_LookupNames for UPN

[Усольцев Пётр]

Hello!
In winbind I can't pass authentication by UPN:
it was tested like this: id  user1 at test.abc on Linux. samba dc install
for upn type names user1 at test.abc you need to filter not on sAMAccountName, but on userPrincipalName.

/etc/nsswitch.conf:
passwd:     files winbind systemd
shadow:     tcb files winbind
group:      files winbind systemd role
 
Or is there a way to enable upn for winbind?
