On these machines, it will be necessary to install the CERN Root Certificates to trust the CERN Certification Authority.

  • Once you have trusted the CERN Root and Trusted Certification Authority certificates, request and import your user certificate in Keychain
  • Make sure that your personal certificate is marked as "This certificate is valid", as shown below:
