I created a certificate for our IIS 6 by sending a request (created with openssl) to our organization's CA. I already had trouble to integrate the private key into that certificate, that has been solved, see SO question
IIS 6.0 now uses the certificate (with TSL v1 and SSL v3), that is the 4th in cert hierarchy. Now, if I access the intranet site, chrome accepts the certificate, so does IE, but Firefox complains about an insecure connection and wants me to add an exceptional rule. If I look into the certificate, how FF presents it to me, I cannot see any of the three issuers.
How can this be? If I connect via
openssl s_client -showcerts -connect... I only see my own certificate too, which is said to be not verified.
I am quite confused now. Where's the mistake and how can I make FF accept certificate without forcing our users to add that exceptionrule?
Maybe do I have to add all the three issuer certificates into cert store of the win2003 server that hosts IIS 6.0 ??
