Trying to update Podcast Producer web front end to own server SSL certificate

Hi,
Does anyone know the steps to connect an SSL certificate (replace the Default.crt) to the Podcast Producer Web interface?
https://:8143

My Mac Xserve Leopard 10.5.6 has been set up with a 3rd party SSL certificate and that works fine.

What I cannot get to work correctly is to replace the Default certificate with the new one. I installed the the PodCast Producer Web application and there is a README file that that is supplied with it and it says to go to
/usr/share/podcastproducer/pcastweb/config/apache/pcastweb.conf.default to modify SSL certificates.

I edited the file to contain the new .crt and .key files and restarted the server. But now when I try to access the https://:8143 web page, it says “this page cannot be found. Once I change it back to the default certificates, the web page is restored.
So I must not be doing something correct.

I need this to work because we authenticate through our Active Directory and I do not want to compromise the user’s username and password.

Thanks for any insight 😀
