The lack of support of the BSD MODES flags in Samba is a known issue that we hope to solve in a future release. We will never be able to support Samba correctly without these bits, but plan on doing a better job in the future.It would be nice if Samba would support the following flags the same as the DOS Attributes. That would solve so many issues:)

BSD hidden Flag  - DOS Attribute Hidden
BSD immutable - Windows Read-Only bit
BSD archived - the reverse of the BSD archive bit 

But the UNIX extensions does not require this support, but this causes the Mac OS Client to have several issue.
