I do not seem to be able to get a single sign on through IE working. It's probably something small and stupid, but to me also very elusive.
The basic setup is rather simple: three windows 2012 machines on a local network. One is a dc with active directory, one is hosting iis (and joined to the domain) and one is used as a client (and joined to the domain).
IIS is configured for Integrated Windows Authorization, and that is the only enabled option for the default site.
On the client, the URL of the IIS machine is added the the intranetzone. IE is configured to use integrated authorization.
Contrary to what I would expect, IE pops up a login screen. When I enter my windows (domain) credentials I stll get access to the site. What am i forgetting?
