The most basic rule, which would allow a named user to run any command as root, would be:
adam	ALL=(ALL) ALL

This permits user adam, logged in at any host (this allows for shared sudoers files across many machines), to run any command as any user.

Are you using the 'visudo' command to do the editing of the /etc/sudoers file? This will validate the file each time.

As requested, here is a working but basic one straight from ubuntu 8.04:
--- SNIP ---

# /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the man page for details on how to write a sudoers file.
# Host alias specification

# User alias specification

# Cmnd alias specification

# Defaults

Defaults        !lecture,tty_tickets,!fqdn

# User privilege specification
root    ALL=(ALL) ALL

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

--- SNIP ---
