MAC OS X 10.8.4 Login Stuck on password - Restart logind service? I have a remote MAC that is stuck on the login screen for the local user. The login screen is stuck right after the password was entered. I can login to the remote MAC with ssh and run commands. This MAC is hosting a database for other users so I would rather not restart it if possible.

Is there a command I can run that would restart the core service logind so that I do not have to restart the computer? 

If the answer is no, can I restart the computer using sudo shutdown -r now remotely over ssh?
It seems like you could run killall loginwindow to restart the login window process which should stop the authentication attempt.

And yes, sudo shutdown -r now should force the remote Mac to reboot immediately.
