SYNOPSIS

pam_lastlog2.so [debug] [silent] [silent_if=<services>] [database=<file>]

DESCRIPTION

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.

OPTIONS

Print debug information.

silent

Avoid all messages except errors and don’t inform the user about any previous login, only update the /var/lib/lastlog/lastlog2.db database.

silent_if=<services>

The argument services is a comma separated list of PAM services. If a service is listed here, the last login message will not be shown.

database=<file>

Use file instead of /var/lib/lastlog/lastlog2.db.

MODULE TYPES PROVIDED

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

RETURN VALUES

EXAMPLES

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.
