+ <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:
