4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Steve French <[email protected]> commit c721c38957fb19982416f6be71aae7b30630d83b upstream. It can be confusing if user ends up authenticated as guest but they requested signing (server will return error validating signed packets) so add log message for this.
