Remediation Templates

Navigate to and open:

/etc/pam.d/system-auth

Remove any existing "pam_faildelay" line and add the following line at the end of the file:
auth       optional pam_faildelay.so delay=4000000

Note: On vCenter appliances, the equivalent file must be edited under "/etc/applmgmt/appliance", if one exists, for the changes to persist after a reboot.
