<samba:parameter name="passdb backend"

		 xmlns:samba="http://samba.org/common">
<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>
	    <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 <link linkend="PRIVATEDIR">
                <parameter moreinfo="none">private dir</parameter></link> 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 <link linkend="LDAPSSL"><parameter moreinfo="none">ldap ssl</parameter></link>) or by
                specifying <parameter moreinfo="none">ldaps://</parameter> in
                the URL argument. </para>
	    </listitem>
			
	    <listitem>
		<para><command moreinfo="none">nisplussam</command> -
		The NIS+ based passdb backend. Takes name NIS domain as
		an optional argument. Only works with sun NIS+ servers.
		</para>
	    </listitem>

		<listitem>
		<para><command moreinfo="none">mysql</command> - 
		The MySQL based passdb backend. Takes an identifier as 
		argument. Read the Samba HOWTO Collection for configuration
		details.
		</para></listitem>

		<listitem>
		<para><command moreinfo="none">guest</command> - 
		Very simple backend that only provides one user: the guest user.
		Only maps the NT guest user to the <parameter>guest account</parameter>.
		Required in pretty much all situations.
		</para></listitem>
