If you simply must keep passwords in sync by having the same passwd file, I highly recommend that you use rsync or scp instead.

Make one system be the authoritative source of the passwd file, and then have the other systems pull the file from there via cronjob. A certain place I worked did this for many thousands of machines with 99-point-many-nines-percent success. Every once in a while a particular machine would fail the pull; the retry next hour usually fixed it without any intervention.

Neither rsync nor scp will require the installation of anyting except for authorized keys so the password file can be copied without requiring the root password.
