The error message about the certificate authority shouldn't be a problem, but who knows, each browser probably works differently. To get rid of this warning message, you need to import the certificate authorities certificate into your browser. For netscape, I converted the file to .der format and created a page to download it into my browser. A similar process probably also applies to MSIE. I'm sure a search on the web will turn up something on how to load the CA's certificate into your browser.
Another thing to check, is to make sure that the common name for the servers certificate matches the FQDN of your server.
Also in your config file above, why do you have ServerPeerVerify set to false? In my config file, I have it set to true.
