Thanks for your report!
I just let my computer suspend by running this command:
sudo pm-suspend
Wasn't prompted for password when wakening up the computer, which would
confirm your observation.
However, I also tried:
sudo systemctl suspend
Then, when wakening up the computer, I was prompted for password as
expected.
So this may be related to the upstart -> systemd transition.

Ubuntu 16.10 x64.
* I let my computer go to sleep.
