A Manual Procedure
Configure the pam.d modules to comply with the locking an account for a minimum of 15 minutes after three unsuccessful logon attempts within a period of 15 minutes with the following command:
1. Enable high-strength passwords:
$ ncli cluster edit-cvm-security-params enable-high-strength-password=true
2. After enabling the high-strength passwords, the system will process the salt stack to enable the DoD versions of the pam.d files. Recheck the Check Text for compliance.
