This is apparently a bug, more precisely a regression (#8) in either Ubuntu's accountservice or lightdm.
This also affects trusty (as I have tested), so adding tag.
There is no patch, yet, removing tag (set in #21), renaming image in #21.
~alisalama has not handled this bug since April, I assume it is not a person, so removing assignment.
Hopefully ~ubuntu-desktop can take a look at this bug sooner or later.
