ERPConnect (Theobald Software): RFC authorization

Question

I want to call a remote SAP function via ERPConnect (Theobald Software):

R3Connection con = new R3Connection("host", 1, "user", "pw", "EN", "700");
con.Open(false);
RFCFunction func = con.CreateFunction("FUNCTION_NAME");

Here I get the following exception:

User ... has no RFC authorization for function group RFC1

Is it generally necessary to have RFC1 group authorization?
