nethserver-password is a module which allows you to easily manage the password Policy (password strength and expiration delays) of NethServer.
first you need to allow my repository, see how to do it
Then you can install it
yum install nethserver-password --enablerepo=stephdl
You can modify the available properties of passwordstrength in the Password panel
# config show passwordstrength passwordstrength=configuration Admin=strong Ibays=strong <----no more used MaxPassAge=180 MinPassAge=0 PassExpires=yes PassWarning=7 Users=strong
You can also for each user disable the password Expiration, you need to go to the relevant User Panel (service Table)
After All, keep in mind that a strong password and a short password expiration are annoying but secure :)
