Check Text (C-75888r1092224_chk)
Verify that OL 9 configures the pam_faillock.so module to exist in the "/etc/pam.d/password-auth" file with the following command:

$ grep pam_faillock.so /etc/pam.d/password-auth
auth required pam_faillock.so preauth
auth required pam_faillock.so authfail
account required pam_faillock.so

If the pam_faillock.so module is not present in the "/etc/pam.d/password-auth" file with the "preauth" line listed before pam_unix.so, this is a finding.
