Gnome remote desktop

There have been some promising advances lately regarding Gnome remote desktop (g-r-d), though it still does not fully work for me, apparently due to “client authentication failure.” Tried various clients, such as Remmina and Gnome connections, to no avail. And yes, I made sure the credentials are the correct ones. Can I please get someone else give g-r-d a quick try, just to confirm (or deny) that what I am doing is correct!

Many thanks!
