[SOLVED] shutdown without password

[televisi]

Resolution located at HERE

Hi All,
I've search through google, and even through this ubuntu forum, but seems all suggestions still not giving me any solution

I'm using Ubuntu server version.

I want to be able to shutdown without asking for password, this is what I do:
sudo visudo and add the following:

user ALL=NOPASSWD: /sbin/shutdown

Now, I try to logout and log back in, and type

shutdown -r now

or

/sbin/shutdown -r now

The above command giving an error message: shutdown: need to be root

I think that error message comes up because the shutdown file is owned by root, right? or wrong?

I try:

sudo shutdown -r now

or

sudo /sbin/shutdown -r now

The above command asking me for [sudo] password

Anything that I miss here?
