<listitem>

    <para>This option allows the administrator to chose which backends
    to retrieve and store passwords with. This allows (for example) both 
    smbpasswd and tdbsam to be used without a recompile. Multiple
    backends can be specified, separated by spaces. The backends will be
    searched in the order they are specified. New users are always added
	to the first backend specified. </para>

    <para>This parameter is in two parts, the backend's name, and a 'location'
    string that has meaning only to that particular backed.  These are separated
    by a : character.</para>

    <para>Available backends can include:
	<itemizedlist>
