Good morning. Our public website is protected by an IIS proxy server featuring basic authentication and SSL (port 443). Unauthenticated (port 80) queries are not served.
I have set up an IIS URL Rewrite rule (reverse proxy, similar to nginx proxy_pass) to rewrite https://iis.mypublicsite/cloud into http://owncloudlinuxserver.private.lan/owncloud. Note that the internal server is not protected at all.
This setup works well via web browser, but the desktop client fails as it does not know how to authenticate itself. Is there a known workaround?
