sudo not working for me (Mac OS X Mavericks)

I am a new ansible user and I can not get the sudo option working for me.

To keep things simple, I am just trying a simple command: “shutdown -r now”

In ansible, I am entering it as: ansible system_name -a “shutdown -r now” --sudo -sudo-user myAdminUser

I have tried this many ways and can not get it working.

Mac also have a console gui that shows all the log files.
