directory mode
This parameter is the octal modes which are
used when converting DOS modes to UNIX modes when creating UNIX
directories.
When a directory is created, the necessary permissions are
calculated according to the mapping from DOS modes to UNIX permissions,
and the resulting UNIX mode is then bit-wise 'AND'ed with this
parameter. This parameter may be thought of as a bit-wise MASK for
the UNIX modes of a directory. Any bit not set
here will be removed from the modes set on a directory when it is
created.
The default value of this parameter removes the 'group'
and 'other' write bits from the UNIX mode, allowing only the
user who owns the directory to modify it.
Following this Samba will bit-wise 'OR' the UNIX mode
created from this parameter with the value of the parameter.
This parameter is set to 000 by default (i.e. no extra mode bits are added).
Note that this parameter does not apply to permissions
set by Windows NT/2000 ACL editors. If the administrator wishes to enforce
a mask on access control lists also, they need to set the .
