One possible problem is the actual file permissions on the server. I
think Samba expects to see the files wide open so that Samba/Winbind can
implement the Windows permissions properly without running afoul of Unix
permissions.
I recognize that this doesn't fit the way the problem developed, but the
symptoms match. :)
