We’ve just started to enable windows authentication on our instances, and I can’t figure out how to make it consistently work. Indeed, SSO is not working at the moment, but i manage to get a windows’ login popup, upon logging in everything is working fine. But if i restart the browser, i can’t get to the page anymore, and get error 500. The log contains
System.InvalidOperationException: An anonymous request was received in between authentication handshake requests.
It turns out I get the popup again if I clear the browser’s cache.
I’ve created SPN entries for the service account running PSU (it is a group managed service account).
We’re running version 4.0.10.
I’m a clueless for now… there seem to be way to run PSU in an IIS setup, perhaps that would be advisable?
