(http://www-archive.mozilla.org/projects/security/pki/nss/ref/ssl/sslerr.html). This means the CA certificate which signed the certificate on the Smartcard is missing in /etc/pki/nssdb which is used by default by SSSD. Recent version of IPA put IPA CA certificates only in /etc/ipa/nssdb, this might be the reason why you see this with F24. To fix this please either add the needed CA certificates to /etc/pki/nssdb with certutil or add 'ca_db = /etc/ipa/nssdb' to the [ssh] section of sssd.conf if /etc/ipa/nssdb already has all needed CA certificates to validate the Smartcard certificate. I'm working on a fix for SSSD to handle handle this change automatically, but unfortunately it is not ready yet.
