This creates a security issue, as the best and most secure way to access a VNC server is through an SSH tunnel where the client will only connect to its localhost on a particular port having all connections through the tunnel to the server's localhost port. If there is a proper way to do this or some sort of work-around, I would be very interested in how to do so. As of right now, this makes LightDM's VNC server unusable for me.
