create mode When a file 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 file. Any bit not set here will be removed from the modes set on a file when it is created. The default value of this parameter removes the 'group' and 'other' write and execute bits from the UNIX modes. Following this Samba will bit-wise 'OR' the UNIX mode created from this parameter with the value of the force create mode parameter which is set to 000 by default. This parameter does not affect directory modes. See the parameter directory mode for details. 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 security mask. force create mode directory mode inherit permissions 0744 0775
