hi Guys I was using a guide to avoid for a user to use the previous password when I set to change password next time I am using this guide http://www.cyberciti.biz/tips/how-to-linux-prevent-the-reuse-of-old-passwords.html it basically says I need to append this line Code: password sufficient pam_unix.so use_authtok md5 shadow remember=10 to the file Code: /etc/pam.d/system-auth but it's not working users can still use previous password any idea guys?
