PAM_LOCALUSER(8)
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.
