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. Three possible values are currently supported: embedded daemon external The classic method is to run every pipe as an internal function embedded in smbd. An alternative method is to fork a daemon early on at smbd startup time. This is supported only for selected pipes. Choosing the external option allows to run a completely independent (3rd party) server capable of interfacing with samba via the MS-RPC interface over named pipes. Currently only the spoolss pipe can be configured in daemon mode like this: rpc_server:spoolss = daemon none
