Check Text ( C-41583r654292_chk )
Verify users are provided with feedback on when account accesses last occurred.

Check that "pam_lastlog" is used and not silent with the following command:

$ grep pam_lastlog /etc/pam.d/login

session required pam_lastlog.so showfailed

If "pam_lastlog" is missing from "/etc/pam.d/login" file, is not "required", or the "silent" option is present, this is a finding.
