Upgraded to v5.9 and Windows Authentication not working

Hi Sharpsharp1,

Thanks for reaching out. It sounds like the 5.9 upgrade may have changed some of the IIS authentication settings. A quick way to check this would be to run the “K2 Configuration Analysis” tool from the Start Menu on the K2 server (make sure to use an account that has admin permissions, for example the K2 Service Account), then click “Analyze All” button, and “Repair” any of the warnings or error messages related to IIS authentication.

Please note, I would not use the “Repair All” button, since that could have a bigger impact.

Additionally, you can verify that there isn't something wrong with the “web.config” file for your individual K2 websites, like "Runtime”, “Identity”, “Identity\Sts\Windows” and “Identity\Sts\Forms” by checking the Authentication settings in IIS for the above mentioned sites and applications.

Thanks Christian,

I did see errors under IIS when using the Config Analysis tool, however if I do repair, it changes my authentiation to Forms which I dont want. When Testing under Forms authentication, it does allow access to forms after logging into the authenticiation, but we had Windows Auth working fine before the upgrade and if selecting Windows Auth, it breaks accesss again.

The web.config look ok, i compared with a previous copy and its looks like v5.9 added extra lines in there like annonymous authenticiation = true in multiple places.
