+<samba:parameter name="rpc_daemon"

+<description>
+ <para>
+ Defines whether to use the embedded code or start a separate daemon
+ for the defined rpc services.
+ The rpc_daemon prefix must be followed by the server name, and a value.
+ </para>
+
+ <para>
+ Two possible values are currently supported:
+ <command moreinfo="none">disabled</command>
+ <command moreinfo="none">fork</command>
+ </para>
+
+ <para>
+ The classic method is to run rpc services as internal daemons
+ embedded in smbd, therefore the external daemons are
+ <emphasis>disabled</emphasis> by default.
+ </para>
+
+ <para>
+ Choosing the <emphasis>fork</emphasis> option will cause samba to fork
+ a separate proces for each daemon configured this way. Each daemon may
+ in turn fork a number of children used to handle requests from multiple
+ smbds and direct tcp/ip connections (if the Endpoint Mapper is
+ enabled). Communication with smbd happens over named pipes and require
+ that said pipes are forward to the external daemon (see <smbconfoption
+ name="rpc_server"/>).
+ </para>
+
+ <para>
+ Forked RPC Daemons support dynamically forking children to handle
+ connections. The heuristics about how many children to keep around and
+ how fast to allow them to fork and also how many clients each child is
+ allowed to handle concurrently is defined by parametrical options named
+ after the daemon.
+ Five options are currently supported:
+ <command moreinfo="none">prefork_min_children</command>
+ <command moreinfo="none">prefork_max_children</command>
+ <command moreinfo="none">prefork_spawn_rate</command>
+ <command moreinfo="none">prefork_max_allowed_clients</command>
+ <command moreinfo="none">prefork_child_min_life</command>
+
+ To set one of these options use the follwing syntax:
+ <programlisting>
+ damonname:prefork_min_children = 5
+ </programlisting>
+ </para>
+
+ <para>
+ Samba includes separate daemons for spoolss and the lsarpc/lsass,
+ netlogon and samr pipes. Currently three daemons are available and they
+ are called:
+ <command moreinfo="none">empd</command>
+ <command moreinfo="none">lsasd</command>
+ <command moreinfo="none">spoolssd</command>
+ Example:
+ <programlisting>
+ rpc_daemon:spoolssd = fork
+ </programlisting>
+ </para>
