Fix Recommendation

Configure OL 9 to enable certificate-based smart card authentication.

Edit the file "/etc/sssd/sssd.conf" and add or edit the following line:

pam_cert_auth = True

Check Contents

Verify that OL 9 has smart cards enabled in System Security Services Daemon (SSSD) if smart cards are used for MFA with the following command:

$ sudo grep pam_cert_auth /etc/sssd/sssd.conf
pam_cert_auth = True

If "pam_cert_auth" is not set to "True", the line is commented out, or the line is missing, this is a finding.
