Check Contents

Note: If smart card authentication is not being used on the system, this requirement is Not Applicable.

Verify that OL 9's System Security Services Daemon (SSSD) prohibits the use of cached authentications after one day.

Check that SSSD allows cached authentications with 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 with 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.
