<H2>DESCRIPTION</H2>
|
|
|
|
<P>
|
|
|
|
<DD>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>
|
|
|
|
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.
