        <para>
        Defines what kind of rpc server to use for a named pipe.
        The rpc_server prefix must be followed by the pipe name, and a value.
        </para>

        <para>
        Three possible values are currently supported:
                <command moreinfo="none">embedded</command>
                <command moreinfo="none">daemon</command>
                <command moreinfo="none">external</command>
        </para>

        <para>
        The classic method is to run every pipe as an internal function
        <emphasis>embedded</emphasis> in smbd.
        </para>

        <para>
        An alternative method is to fork a <emphasis>daemon</emphasis>
        early on at smbd startup time. This is supported only for selected
        pipes.
        </para>

        <para>
        Choosing the <emphasis>external</emphasis> option allows to run a
        completely independent (3rd party) server capable of interfacing
        with samba via the MS-RPC interface over named pipes.
        </para>

        <para>
        Currently only the spoolss pipe can be configured in
        <emphasis>daemon</emphasis> mode like this:
        <programlisting>
        rpc_server:spoolss = daemon
        </programlisting>
        </para>
