I was asked to create a sharepoint web application with ssl on a server with sharepoint 2010 installed. The problem is that this port seems to be in use for hosting our subversion repository. So when i try to browse my sharepoint site, it just shows a page with my repository. I've read about installing certificates and configuring multiple sites on one port with host headers but i never succeeded to complete this job. I would really appreciate some help here.
Thanks!
Assuming you're talking about individual SSL certificates (as opposed to a single wildcard certificate), I believe each website HAS to have its own IP address. AFAIK it is not possible to run multiple websites with multiple SSL certificates under the same IP address.
Depending on who is hosting the server, you would need a new IP address to be allocated to the server, and then within IIS you use the new IP address against the hostheader of your new website. You should find that the certificate works correctly, if not then try removing the certificate from the website and re-allocating it.
You would only be able to use a wildcard certificate if the primary domains of the websites were the same (e.g. website1.mydomain.com and website2.mydomain.com).
