Section: Linux-PAM Manual (8)
:pam_lastlog.so [debug] [silent] [never] [nodate] [nohost] [noterm] [nowtmp] [noupdate] [showfailed] [inactive=<days>]
Some applications may perform this function themselves. In such cases, this module is not necessary.
If the module is called in the auth or account phase, the accounts that were not used recently enough will be disallowed to log in. The check is not performed for the root account so the root is never locked out.
The auth and account module type allows to lock out users which did not login recently enough. The session module type is provided for displaying the information about the last login and/or updating the lastlog and wtmp files.
Add the following line to /etc/pam.d/login to display the last login time of an user:
session required pam_lastlog.so nowtmp
To reject the user if he did not login during the previous 50 days the following line can be used:
auth required pam_lastlog.so inactive=50
