The PAM stack is modified, adding lines for pam_faillock.so. The line with authfail line is inserted "after pam_unix.so". When there are alternative authentication methods (ex: pam_krb5.so or pam_sssd.so), this breaks them. It would be better to add this line "before pam_deny.so" instead. This would still have the desired effect, without breaking alternative authentication methods. What's the best path to get this change made? Thanks.
