The list of available users shown at the login screen is cleared after each reboot. Once you have confirmed that everything is working you can, however, optionally configure the graphical login screen to hide the names of both local users and SME users who have recently logged in.

Edit /etc/lightdm/lightdm.conf and add the following line
