3 <listitem><para>This parameter controls what UNIX permission bits
4 can be modified when a Windows NT client is manipulating the UNIX
5 permission on a directory using the native NT security dialog
8 <para>This parameter is applied as a mask (AND'ed with) to
9 the changed permission bits, thus preventing any bits not in
10 this mask from being modified. Essentially, zero bits in this
11 mask may be treated as a set of bits the user is not allowed
14 <para>If not set explicitly this parameter is set to 0777
15 meaning a user is allowed to modify all the user/group/world
16 permissions on a directory.</para>
18 <para><emphasis>Note</emphasis> that users who can access the
19 Samba server through other means can easily bypass this restriction,
20 so it is primarily useful for standalone "appliance" systems.
21 Administrators of most normal systems will probably want to leave
22 it as the default of <constant>0777</constant>.</para>
