> 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.
