Fix Recommendation

Configure RHEL 10 SSSD to prohibit the use of cached authentications after one day.

Edit the file "/etc/sssd/sssd.conf" or a configuration file in "/etc/sssd/conf.d" and add or edit the following line just below the line [pam]:

offline_credentials_expiration = 1

Restart the "sssd" service with the following command for the changes to take effect:

$ sudo systemctl restart sssd.service

Check Contents

Verify RHEL 10 System Security Services Daemon (SSSD) prohibits the use of cached authentications after one day with the following command:

Note: Cached authentication settings should be configured even if smart card authentication is not used on the system.

Determine if SSSD allows cached authentications with the following command:

$ sudo grep -irs cache_credentials /etc/sssd/sssd.conf /etc/sssd/conf.d/ | grep -v "^#"
cache_credentials = true

If "cache_credentials" is set to "false" or missing from the configuration file, this is not a finding and no further checks are required.

If "cache_credentials" is set to "true", check that SSSD prohibits the use of cached authentications after one day with the following command:

$ sudo grep -irs offline_credentials_expiration /etc/sssd/sssd.conf /etc/sssd/conf.d/ | grep -v "^#"
offline_credentials_expiration = 1

If "offline_credentials_expiration" is not set to a value of "1", this is a finding.
