<description>
    <para>
	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 <emphasis>not</emphasis> set here will
	be removed from the modes set on a file when it is created.
	</para>

    <para>
	The default value of this parameter removes the <literal>group</literal> and <literal>other</literal>
	write and execute bits from the UNIX modes.
	</para>

    <para>
	Following this Samba will bit-wise 'OR' the UNIX mode created from this parameter with the value of the
	<smbconfoption name="force create mode"/> parameter which is set to 000 by default.
	</para>

    <para>
	This parameter does not affect directory masks. See the parameter <smbconfoption name="directory mask"/>
	for details.
