I've installed ADFS 2.0 on a Windows Server 2008R2, and after installation / configuration wizard I only see the error page when I access "https://myServer/adfs/ls/"
I see a reference number but no entry in the event Viewer. If I create a Wif demo application with the WIF SDK / FedUtil and enter the ADFS Server as existing STS I can find an error in the even Viewer (A token request was received for a relying party identified by the key 'https://localhost/wifdemo1', but the request could not be fulfilled because the key does not identify any known relying party trust). I've added my demo app in ADFS as RP.
I've used a Self-Signed Certificate for the ADFS installation. I think something with the configuration of my ADFS is not Ok. Can someone please provide me some ideas what may be wrong?
