I've been debugging the OCSP issue as well and we can see that the OCSP server responds to the request. This response is signed by a cert which is issued by our CA, and that cert is indeed in my nssdb. So should this not work? Do I have to have the actual OCSP server cert in nssdb, does certificate chaining not work here?
