Hidden,System Attributes on Directories

[Nick Eggleston]

Setting Hidden, System, or Archive bits on DIRECTORIES does not work
(Samba Ver 2.2.2) .  We have it working fine for files, where is maps
those permissions to the X flags under Unix.  However, directories on Unix
require those bits for normal operation, so they would have to be mapped
to some other bits (probably suid, sgid and sticky bits) for directories.
Unfortunately, I can find no configuration parameters that discuss this
issue.

[the only other option I can see would me to have a secret look-aside file
that stored these setting out-of-band]

Would someone(s) please comment on this issue?  Has it been addressed
previously?  Am I just missing something obvious?

Thanks!
