[Parag Gupta]

i tried to create setting below to implement cis check (Ensure lockout for failed password attempts is configured)

auth required pam_faillock.so preauth audit silent deny=5 unlock_time=900 

auth sufficient pam_unix.so 

auth [default=die] pam_faillock.so authfail audit deny=5 unlock_time=900 

auth sufficient pam_faillock.so authsucc audit deny=5 unlock_time=900

But this setting is not working . Can you guide me how can  i implement this check on coreOS .
