       pam_lastlog2 is a PAM module to display a line of information about the last login of the user. The
       module uses the /var/lib/lastlog/lastlog2.db database file to store all information.

       Compared to pam_lastlog this PAM module is Y2038 safe and uses sqlite3 to store the information.

       Add the following line to e.g. /etc/pam.d/login to display the last login time of a user:

       session  optional pam_lastlog2.so silent_if=gdm,gdm-password

       It is up to the administrator to decide if the user can login (optional/required) when pam_lastlog2 has
       returned an error.

       The session module type is provided for displaying the information about the last login and updating the
       lastlog file.
