+    <title>DESCRIPTION</title>
+
+    <para>
+      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 <filename>/var/log/lastlog</filename> file.
+    </para>
+    <para>
+      Some applications may perform this function themselves. In such
+      cases, this module is not necessary.
+    </para>
+    <para>
+      The module checks <option>LASTLOG_UID_MAX</option> option in
+      <filename>/etc/login.defs</filename> and does not update or display
+      last login records for users with UID higher than its value.
+      If the option is not present or its value is invalid, no user ID
+      limit is applied.
+    </para>
+    <para>
+      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. It is also not performed for users with UID higher
+      than the <option>LASTLOG_UID_MAX</option> value.
