I just went to shut down my laptop and it asked me to authenticate before I could reboot. This has never happened before, so I figured maybe a recent update changed something. After a quick search, I found that this happens when multiple users are logged in. ...odd. I'm the only one logged in. Or am I?

nathanbrauer@beast:~$ who --all
           system boot  2015-09-24 13:30
           run-level 2  2015-09-24 13:30
LOGIN      tty4         2015-09-24 13:30              1247 id=4
LOGIN      tty5         2015-09-24 13:30              1251 id=5
LOGIN      tty2         2015-09-24 13:30              1257 id=2
LOGIN      tty3         2015-09-24 13:30              1258 id=3
LOGIN      tty6         2015-09-24 13:30              1261 id=6
LOGIN      tty1         2015-09-24 13:30              1774 id=1
nathanbrauer ? :0           2015-09-24 13:30   ?          1991 (:0)
nathanbrauer + pts/0        2015-09-25 09:35   .          4173 (:0)
           pts/2        2015-09-25 08:40                 0 id=/2    term=0 exit=0

One of those logins is the tty7/regular login, the other is the terminal I'm running to open the command.

So, why is shutdown asking for authentication even when I exit all terminals?

Adding this as an answer then:

That's generally a symptom of having a daemon that has been started with sudo.
