> When a non-secured client tries to connect to a secured server, the first indication is an error from RpcConnection::HandleRpcRespose complaining about "RPC response with Unknown call id -33".
> We should insert code in HandleRpcResponse to detect if the unknown call id == RpcEngine::kCallIdSasl and return an informative error that you have an unsecured client connecting to a secured server.
