NAME

6       pam_localuser - require users to be listed in /etc/passwd
7

SYNOPSIS

9       pam_localuser.so [debug] [file=/path/passwd]
10

DESCRIPTION

12       pam_localuser is a PAM module to help implementing site-wide login
13       policies, where they typically include a subset of the network's users
14       and a few accounts that are local to a particular workstation. Using
15       pam_localuser and pam_wheel or pam_listfile is an effective way to
16       restrict access to either local users and/or a subset of the network's
17       users.
18
19       This could also be implemented using pam_listfile.so and a very short
20       awk script invoked by cron, but it's common enough to have been
21       separated out.
