pam_lastlog -- PAM module to display date of last login and perform inactive
account lock out

   --------------------------------------------------------------------------

DESCRIPTION

   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.

OPTIONS

   debug

           Print debug information.

   silent

           Don't inform the user about any previous login, just update the
           /var/log/lastlog file. This option does not affect display of bad
           login attempts.

   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.

   unlimited

           If the fsize limit is set, this option can be used to override it,
           preventing failures on systems with large UID values that lead
           lastlog to become a huge sparse file.

EXAMPLES

   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
