I have an x.509 Certificate, an RSA Private Key and an Intermediate CA Certificate. All in PEM format. They are valid, wildcard certificates and were provided to me by our web developers. I am installing Zimbra 8.0 NE and need to get that certificate installed. Why do they require the generation of a CSR. I generated one and now it is asking for Certificate, Root CA and Intermediate CA. I can't determine how those correlate to what I have. A little clarifying direction would be appreciated.

Thanks,
Stephen
