[Samba] Samba4 DC/AD documents created in redirected folders with bogus UID

[Guilherme Boing]

I just noticed that my fresh install of Samba 4.2.3 has the same behaviour.

I have a share (\\samba\it_share)) and some users when creating files have
the UID as 3000000 and some have their correct UIDs.
Share permissons are being controlled by Windows ACLs.
