+<description>
+
+    <para>This option allows the administrator to chose which backend
+    will be used for storing user and possibly group information.  This allows 
+    you to swap between different storage mechanisms without recompile. </para>
+
+    <para>The parameter value is divided into 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>
+	    <listitem>
+		<para><command moreinfo="none">smbpasswd</command> - The default smbpasswd
+		backend. Takes a path to the smbpasswd file as an optional argument.
+		</para>
+	    </listitem>
+			
+	    <listitem>
+		<para><command moreinfo="none">tdbsam</command> - The TDB based password storage
+                backend.  Takes a path to the TDB as an optional argument (defaults to passdb.tdb 
+                in the <smbconfoption name="private dir"/> directory.</para>
+	    </listitem>
+			
+	    <listitem>
+		<para><command moreinfo="none">ldapsam</command> - The LDAP based passdb 
+                backend.  Takes an LDAP URL as an optional argument (defaults to 
+                <command moreinfo="none">ldap://localhost</command>)</para>
+			
+		<para>LDAP connections should be secured where possible.  This may be done using either
+                Start-TLS (see <smbconfoption name="ldap ssl"/>) or by
+                specifying <parameter moreinfo="none">ldaps://</parameter> in
+                the URL argument. </para>
+
+                <para>Multiple servers may also be specified in double-quotes.
+		Whether multiple servers are supported or not and the exact
+		syntax depends on the LDAP library you use.
+		</para>
+
+	    </listitem>
+	</itemizedlist>
+
+    </para>
+	Examples of use are:
+<programlisting>
+passdb backend = tdbsam:/etc/samba/private/passdb.tdb 
+
+or multi server LDAP URL with OpenLDAP library:
+
+passdb backend = ldapsam:"ldap://ldap-1.example.com ldap://ldap-2.example.com"
+
+or multi server LDAP URL with Netscape based LDAP library:
+
+passdb backend = ldapsam:"ldap://ldap-1.example.com ldap-2.example.com"
+</programlisting>
