Authenication seems to be working but it looks like it returns an unexpected string value it can't handle. I tested the azure app and CAS token using powershell and no issues. So last ditch effort was to try on another server. This happend to be a Linux server. When i set the app up there everything worked without issues. This made me think that the Graph and CAS inputs does not work on Windows servers since this was the only difference. So i tested on an another windows server and got the same error. So I wondered if anyone else here has the same result as me, or has managed to get this running on a windows server? The app in splunk says it is platform independent, so it should run on windows to.
