Samba4 already has the Windows 2008 schema loaded for this exact
purpose.  We have not yet taken any steps to automatically allocate
uidNumber values into the directory (nor do we use those for the Samba4

If you fill in the uidNumber attribute, the rest *should* work (do let
me know how well it works, please).
