The issue is not a lightdm one if the user is still is the nopasswdlogin group, can't reproduce it on a xenial installation though. When you set the new password the change stick to the UI, it reflects after validating that a password has been set? Doing those steps on a test install the user is removed from the group when the new password is set...
