PAM_LOCALUSER
PAM_LOCALUSER
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.
