      The lis_result_sourcedid identifies the cell in the gradebook associated with the current user and current launch link. If the "Accept grades from the tool" option is not selected no grades should be accepted for the link and so there is no point sending the lis_result_sourcedid parameter. A tool provider may already have the service endpoint from launches from other links and so attempt to access this gradebook column. Attempts to do so are denied, but the presence of the parameter is potentially confusing to a tool provider who may think that the service is available because it has been passed.
