 ====================
 
+New samba-dcerpcd binary to provide DCERPC in the member server setup
+---------------------------------------------------------------------
+
+In order to make it much easier to break out the DCERPC services
+from smbd, a new samba-dcerpcd binary has been created.
+
+samba-dcerpcd can be used in two ways. In the normal case without
+startup script modification it is invoked on demand from smbd or
+winbind --np-helper to serve DCERPC over named pipes. Note that
+in order to run in this mode the smb.conf [global] section has
+a new parameter "rpc start on demand helpers = [true|false]".
+This parameter is set to "true" by default, meaning no changes to
+smb.conf files are needed to run samba-dcerpcd on demand as a named
+pipe helper.
+
+It can also be used in a standalone mode where it is started
+separately from smbd or winbind but this requires changes to system
+startup scripts, and in addition a change to smb.conf, setting the new
+[global] parameter "rpc start on demand helpers = false". If "rpc
+start on demand helpers" is not set to false, samba-dcerpcd will
+refuse to start in standalone mode.
+
+Note that when Samba is run in the Active Directory Domain Controller
+mode the samba binary that provides the AD code will still provide its
+normal DCERPC services whilst allowing samba-dcerpcd to provide
+services like SRVSVC in the same way that smbd used to in this
+configuration.
+
+The parameters that allowed some smbd-hosted services to be started
+externally are now gone (detailed below) as this is now the default
+setting.
+
+samba-dcerpcd can also be useful for use outside of the Samba
+framework, for example, use with the Linux kernel SMB2 server ksmbd or
+possibly other SMB2 server implementations.
