[Samba] Authenticate using AD UPN name

I think it is not yet possible because Winbind (when retrieving user from
AD) is not yet meant to be configured to much, it is meant to produce
Windows equivalent users for these users, on Linux side, use the
information as on Windows clients side. This because when accessing a Samba
share from a Windows client with a Samba AD account, on file server side
the user must have same information as in windows (for file ownership).
Following same idea Winbind is (or was) not meant to use uidNumber /
gidNumber for user on linux side as these information are related to the
Linux/UNIX part of users.
In other words: in windows the default group of a user into an AD domain is
"domain users". In gidNumber you could use anything that suit your needs.
When a AD user connected on Windows client creates some file on Samba file
server, the group of newly created file should be "Domain users" and not
the content of gidNumber which is Linux/UNIX main group.
Anyway, I'm not winbind specialist and I could have missed something.
Someone would correct me in that case ;)
