PAM_LOCALUSER(8)               Linux-PAM Manual               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.
