== Extended Validation Rules ==
In order to receive the EV UI, end-entity revocation checking must succeed via one of the currently implemented revocation checking mechanisms described above. In addition, as part of EV processing, OCSP is used in addition to OneCRL to check revocation for intermediate CA certificates. If an OCSP response for the intermediate CA certificate is not received or fails to verify, then the EV UI will not be displayed. Finally, if the security.OCSP.enabled preference is set to ‘0’ (disabled), OCSP checking is not performed and the EV UI will not appear for otherwise valid EV certificates.
