The requested page requires a valid SSL client certificate

The account to which your client certificate is mapped on the Web server has been denied access to this Web site. A Secure Sockets Layer (SSL) client certificate is used for identifying you as a valid user of the resource.

Please try the following:

  • Contact the Web site administrator to establish client certificate permissions.
  • If you already have a valid client certificate, use your Web browser's security features to ensure that your client certificate is installed properly. (Some Web browsers refer to client certificates as browser or personal certificates.)
  • Change your client certificate and click the Refresh button, if appropriate.
