Default my (simple) sudoers doesn't work

Hello,

I wish to halt|shutdown| sleep my machine as an unprivilegied user on
the command-line or via the menu of a light window-manager.

Here's my /etc/sudoers

Defaults env_reset

# User alias specification
User_Alias STOP = gv

# Cmnd alias specification
Cmnd_Alias SLEEP = /usr/sbin/acpitool -S
Cmnd_Alias HALT = /usr/sbin/halt
Cmnd_Alias REBOOT = /usr/sbin/reboot

# User privilege specification
root ALL=(ALL) ALL

# Uncomment to allow members of group sudo to not need a password
# (Note that later entries override this, so you might need to move
# it further down)
# %sudo ALL=NOPASSWD: ALL

STOP ALL= NOPASSWD: SLEEP, HALT, REBOOT

The only thing I got to work is to insert

gv ALL=(ALL) ALL

But in all other configurations,

gv ALL = /usr/sbin/acpitool -S
gv ALL = SLEEP

the response I get is:

gv@fantasio:~$ sudo halt

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.

[sudo] password for gv:
Sorry, user gv is not allowed to execute '/sbin/halt' as
root on fantasio.champignac.

What is the mistake ? (I use visudo and sudo 1.6.9p17-3 on Lenny)

Thanks in advance,

Try putting a wildcard at the end. Presumably you're actually running
something like "halt now", correct? So sudoers, I think, should show
the command as "/usr/sbin/halt *"
