Bug Description
After Bazaar revision 2006, lightdm supports "auto relogin", something similar to AutoLoginAgain in kdm.
In my tests, I've set lightdm to autologin as guest after a timeout of 30 seconds:
[SeatDefaults]
autologin-
autologin-
However, if I log in as another user and lock its session (using light locker), lightdm performs an automatic login as guest on top of my locked session. I guess it's due to the fact that light locker uses lightdm greeter to lock screen, so when it's displayed, it triggers another autologin timeout.
This is specially bad for non-seat0 seats, when you have no user-switching mechanism available, and an autologin over a locked session can hang the seat completely.
