<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>
