Certificate issue is resolved.. You don't need to use a CA signed cert, you can use a self signed one.
Browse to the URL of the site with Internet Exploder running as administrator (
https://yoursite.com ), you'll get a certificate error. Click on the certificate and you'll be able to install it as a CA. Once you've done that, Altium ( which obviously is using some OS stuff rather than its own code, forutatly ), will trust that cert.
My SVN server is running on Linux, Apache and SVN.. I had to create a new certificate for it, this is so the certificate name matches the host name. All those things are easy.
However.. Now i've got a new problem, and its not authenticating properly.. Using SVN from the command line, it all works just fine... but that kind of defeats the purpose, of doing this..
Theres virtually no references in google to using SVN and Altium.
