<title>DESCRIPTION</title>
<para>
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.
</para>
<para>
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.
