Marco, I can reproduce that with 100% reliability on my 16.04 beta (with
all the updates installed). When I see the auth dialog (i.e. after
locking the screen or returning from sleep), I hit ctrl+alt+F6
ctrl+alt+F7 and gain access to my system. During the process, nothing at
all gets added to /var/log/auth.log
