Looks like someone used their new-found abilities in sudo and corrupted your password file, or did something equally bad. Boot to single-user mode (type -s at the boot: prompt), mount up / read-write (mount -u /), then look for damage. I assume you modified /usr/local/etc/sudoers using `visudo' so that not just anyone could get full root access using their password?
