This is the issue with being unable to map these SIDs to posix
identities? We need idmap (no, not again!), but in the meantime we can
have as-root access by setting 'ntvfs handler = default' rather than the
default of 'ntvfs handler = unixuid default'.
For my work with Samba4, I'm looking to develop a 'everybody is nobody'
solution (which is all the particular task I have requires). But adding
a real idmap shouldn't be too hard however...

We should be falling back - I'll work on that logic.
