Hello, Yeah, what an "advance" in software. I need a display manager that saves the last session type of every user in the user's home directory and has options to configure the requirement of root authentication for reboot or shutdown from the greeter. kdm had both of these features, sddm has none. Additionally, after setting appropriate policykit rules, when an X session was ended with "Shutdown" or "Reboot", a small window for root authentication appeared. With sddm, such a window does not appear any more - but at least, the system is not shutdown/rebooted. Worse, none of the display manager packages available in Ubuntu 16.04 seems to have the desired features. Not to mention that, in my personal opinion, all of the greeter screens look ugly.
