pam_localuser - require users to be listed in /etc/passwd
pam_localuser.so [debug] [file=/path/passwd]
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.
Print debug information.
Use a file other than /etc/passwd.
