Symptoms

Consider the following scenario:
  • You install a custom certificate validation module in Internet Information Services (IIS) 7.5 or IIS 8.0.
  • You host a Web application or Web service that accepts a self-signed certificate for validation in IIS.
  • An HTTPS request that uses a self-signed certificate from a client computer is sent to the Web application or Web service.
In this scenario, the client computer may receive an "HTTP 403 (Forbidden)" error message.

Cause

This issue occurs because IIS rejects the self-signed certificate before it reaches the custom certificate validation module.

Note This issue typically occurs when you use a large-sized certificate.

Resolution
