Name
pam_localuser - require users to be listed in /etc/passwd
Synopsis
| pam_localuser.so [debug] [file=/path/passwd] | |
DESCRIPTION
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.
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.
