pam_lastlog - PAM module to display date of last login and perform
inactive account lock out
pam_lastlog.so [debug] [silent] [never] [nodate] [nohost] [noterm]
[nowtmp] [noupdate] [showfailed] [inactive=<days>]
pam_lastlog is a PAM module to display a line of information about
the last login of the user. In addition, the module maintains the
/var/log/lastlog file.
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.
debug
Print debug information.
silent
Don't inform the user about any previous login, just update the
/var/log/lastlog file.
never
If the /var/log/lastlog file does not contain any old entries for
the user, indicate that the user has never previously logged in
with a welcome message.
nodate
Don't display the date of the last login.
noterm
Don't display the terminal name on which the last login was
attempted.
nohost
Don't indicate from which host the last login was attempted.
nowtmp
Don't update the wtmp entry.
noupdate
Don't update any file.
showfailed
Display number of failed login attempts and the date of the last
failed attempt from btmp. The date is not displayed when nodate
is specified.
inactive=<days>
This option is specific for the auth or account phase. It
specifies the number of days after the last login of the user
when the user will be locked out by the module. The default value
is 90.
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.
PAM_SUCCESS
Everything was successful.
PAM_SERVICE_ERR
Internal service module error.
PAM_USER_UNKNOWN
User not known.
PAM_AUTH_ERR
User locked out in the auth or account phase due to inactivity.
PAM_IGNORE
There was an error during reading the lastlog file in the auth or
account phase and thus inactivity of the user cannot be
determined.
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
/var/log/lastlog
Lastlog logging file
pam.conf(5), pam.d(5), pam(8)

Inactive account lock out added by Tomáš Mráz <tm@t8m.info>.
