AustrianGrid Certification Authority

New Root Certificate

2006-09-06

The problems encountered when using Microsoft Internet Explorer and Outlook and certificates issued by the AustrianGrid CA have been solved.
The cause were unnecessary usage entries in the AustrianGrid CA Root Certificate that triggered Microsoft Windows to refuse to accept the end-entity certificates.
As of now the secure communication (HTTPS) between IE and the AustrianGrid CA web pages is possible. It is also possible to sign e-mails and verify the signature of received messages using Outlook.

You must replace the old AustrianGridCA Root Certificate for all web browsers as soon as possible!!! Otherwise you may encounter all kind of error messages (e.g. duplicate certificate for the same serial number, etc).

On all Microsoft Windows systems the certificate administration is done at the system level. Therefore go to Internet options -> Content -> Certificates (from within the system level, IE or Outlook) and delete the old AustrianGrid CA Root Certificate.

For all browsers except IE (Mozilla, Seamonkey, Firefox, etc.) running under all operating systems open the browser, got to Preferences, go to the certificate administration and delete the old AustrianGrid CA Root Certificate.

Finally open the web page Root Certificate & CRL and "Dowload into the browser" or save the Root Certificate on a file and "import" it into your browser and mail client (e.g. Thunderbird).
