Assume the following scenario:
- A user or application accesses a web page or web application running on an Internet Information Services (IIS) web server.
- The web server is configured to request a client certificate for the requested resource.
- Although there is a valid client certificate on the client, the error code 403 Forbidden is returned immediately. The user is not prompted (when calling the page with a browser) to select a certificate.
- The web server certificate was recently renewed and the IIS SSL binding was configured accordingly via the IIS Manager.
403 - Forbidden: Access is denied. You do not have permission to view this directory or page using the credentials that you supplied.Continue reading „HTTP Fehlercode 403 bei Anmeldung mittels Client-Zertifikat an Internet Information Services (IIS) nach Erneuerung des Webserver-Zertifikats“
