CentOS / RedHat: Set Password Quality Requirements

Posted on in Categories , , , , , , last updated October 1, 2009

I‘ve created a unique default group for each user and also used Linux groups to enhance security. Further a group called “users” allowed to login via ssh. However, I need to enforce password quality-control for all users. How do I create a password policy and enforce its use under CentOS or RHEL 5.x server operating systems?
