<samba:parameter xmlns:samba="http://samba.org/common">
<term><anchor id="DIRECTORYMASK"/>directory mask (S)</term>
<listitem><para>This parameter is the octal modes which are
used when converting DOS modes to UNIX modes when creating UNIX
directories.</para>
<para>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 <emphasis>not</emphasis> set
here will be removed from the modes set on a directory when it is
created.</para>
<para>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.</para>
<para>Following this Samba will bit-wise 'OR' the UNIX mode
created from this parameter with the value of the <link linkend="FORCEDIRECTORYMODE"><parameter moreinfo="none">force directory mode
</parameter></link> parameter. This parameter is set to 000 by
default (i.e. no extra mode bits are added).</para>
<para>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 <link linkend="DIRECTORYSECURITYMASK"><parameter moreinfo="none">directory security mask</parameter></link>.</para>
<para>See the <link linkend="FORCEDIRECTORYMODE"><parameter moreinfo="none">force
directory mode</parameter></link> parameter to cause particular mode
bits to always be set on created directories.</para>
<para>See also the <link linkend="CREATEMODE"><parameter moreinfo="none">create mode
</parameter></link> parameter for masking mode bits on created files,
and the <link linkend="DIRECTORYSECURITYMASK"><parameter moreinfo="none">directory
security mask</parameter></link> parameter.</para>
<para>Also refer to the <link linkend="INHERITPERMISSIONS"><parameter moreinfo="none">
inherit permissions</parameter></link> parameter.</para>
<para>Default: <command moreinfo="none">directory mask = 0755</command></para>
<para>Example: <command moreinfo="none">directory mask = 0775</command></para>
