how to import a zimbra trusting cert into IE

Well, I finally made some progress. Of course, being relatively new to CAs, certificate trust chains, etc. I ended up wasting half my day figuring it out.

Most of the research I did pointed to importing the certificate presented to the browser when using the ZWC into the Trusted Root Certification Authorities store, which no matter how many dozens of ways I did it made no difference. I ended up going into /opt/zimbra/ssl/zimbra/ca and converting the PEM format ca.pem certificate into Windows compatible DER format:

openssl x509 -inform PEM -in ca.pem -outform DER -out ca.cer

Then I imported this into the Trusted Root Certification Authorities store and finally I’m not getting the warnings from IE.

I did have one more question for anyone knowledgeable with certificates and domains/DNS. I’d like to use the servers host name as the URL instead of the FQDN (e.g. https://mail/ instead of to simplify things, but of course the browser then complains the URL doesn’t match the certificate (issued to Anyone know if this is possible without getting the warnings? I tried to create a certificate using just the hostname but it requires a proper domain name.
