Check Text (C-282597r1200771_chk)
Verify the System Security Services Daemon (SSSD) prohibits the use of cached authentications after one day.
Note: If smart card authentication is not being used on the system, this requirement is not applicable.
Check that SSSD allows cached authentications using the following command:
$ sudo grep cache_credentials /etc/sssd/sssd.conf
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 using the following command:
$ sudo grep offline_credentials_expiration /etc/sssd/sssd.conf
offline_credentials_expiration = 1
If "offline_credentials_expiration" is not set to a value of "1", this is a finding.
Fix Text (F-87063r1200770_fix)
Configure the SSSD to prohibit the use of cached authentications after one day.
Add or change the following line in "/etc/sssd/sssd.conf" just below the line [pam]:
offline_credentials_expiration = 1
