I have a working test application that uses Windows Idendity Foundation SDK and ADFS 2.0 for authentication, which runs on Windows Server 2008 R2, IIS 7.5, Integrated managed pipeline application pool mode.
My problem is that the "real" application I need to setup with this kind of authentication can only run on Classic managed pipeline application pool mode due to a legacy code, and when I select it I recieve an "HttpException (0x80004005): Failed to Execute URL" error.
Does anyone have an idea how to solve this problem?
UPDATE:
I have found out that https://example.com/myapplicatio/ gives me the error, but https://example.com/myapplicatio/Default.aspx works.

I'm having the same issue. Here is another discussion elsewhere that is similar. Did you wind up solving your problem?
