      pam_localuser is a PAM module to help implementing site-wide login
      policies, where they typically include a subset of the network's
      users and a few accounts that are local to a particular workstation.
      Using pam_localuser and pam_wheel or pam_listfile is an effective
      way to restrict access to either local users and/or a subset of the
      network's users.
    </p><p>
      This could also be implemented using pam_listfile.so and a very
      short awk script invoked by cron, but it's common enough to have
      been separated out.
