Description
Enforcing a minimum password lifetime helps prevent repeated password changes to defeat the password reuse or history enforcement requirement. If users are allowed to immediately and continually change their password, the password could be repeatedly changed in a short period of time to defeat the organization's policy regarding password reuse.

Fix Text (F-65025r996590_fix)
Configure SLEM 5 to enforce 24 hours/one day or greater as the minimum password age for user accounts.

> sudo passwd -n 1 <username>
