ALMA-09-038630 - AlmaLinux OS 9 must prohibit the use of cached authenticators after one day.
Information
Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. If the information system or application allows the user to consecutively reuse their password when that password has exceeded its defined lifetime, the end result is a password that is not changed as per policy requirements.If cached authentication information is out-of-date, the validity of the authentication information may be questionable.
Solution
Configure the SSSD to prohibit the use of cached authentications after one day.Add/modify the following line in "/etc/sssd/sssd.conf" (or a conf file in /etc/sssd/conf.d/) just below the line [pam]:
offline_credentials_expiration = 1
