Fix Recommendation

Configure Ubuntu 24.04 LTS to do certificate status checking for multifactor authentication.

Modify all of the "cert_policy" lines in "/etc/pam_pkcs11/pam_pkcs11.conf" to include "ocsp_on".

Check Contents

Verify Ubuntu 24.04 LTS electronically verifies PIV credentials via certificate status checking with the following command:

$ sudo grep use_pkcs11_module /etc/pam_pkcs11/pam_pkcs11.conf | awk '/pkcs11_module opensc {/,/}/' /etc/pam_pkcs11/pam_pkcs11.conf | grep cert_policy | grep ocsp_on

cert_policy = ca,signature,ocsp_on;

If every returned "cert_policy" line is not set to "ocsp_on", or the line is commented out, this is a finding.
