why are you using fedora 14?? It's out of date and NOT a server distro. Use CentOS if you want a "free" server for the job.
But you want to import the certificate? Why? That's for OWA to serve to Apache as a client, not for Apache to be configured with. Why use SSL on the Serverside at all though? It's totally normal to remove SSL there once it's through apache.
