this is my sudoers to allow mortal users to shutdown (APAGAR)

# Host alias specification

Host_Alias LOCAL=localhost

# User alias specification

User_Alias MORTALES=leda,camila,loreto,rod

# Cmnd alias specification

Cmnd_Alias APAGAR=/sbin/poweroff,/sbin/reboot,/sbin/halt

# Defaults

Defaults        !lecture,tty_tickets   ## what is this?

#################################

MORTALES        LOCAL=(root)NOPASSWD:APAGAR
#how i read it: MORTALs from LOCAL machine can as (root) without password 
run APAGAR

root    ALL=(ALL) ALL
# root can from everywhere as anybody run anything

# Added by Ubuntu installer
