Symptoms
Consider the following scenario:
-
An Online Certificate Status Protocol (OCSP) responder obtains a Response Signing certificate from a Windows Server 2008 certification authority (CA).
-
Some third-party OCSP clients use this OCSP server to verify certificates.
In this scenario, these OCSP clients may reject a response from the OCSP responder. When the response is rejected, a function failure occurs for some third-party OCSP clients, such as Cisco routers.
Cause
A Windows Server 2008 CA issues a Response Signing certificate to an OCSP responder. The NoRevCheck extension of this certificate contains a zero-length value instead of an ASN null value. The OCSP responder uses this certificate to respond to queries from OCSP clients.Some third-party OCSP clients require that the value of the NoRevCheck extension is an ASN null value. Therefore, these third-party OCSP clients reject the response from the OCSP responder.
