Ok, but that's not an error. I just scanned for anything that appeared to
be an actual error.

The message though is not ideal since that "missing" setting does not work
on IIS. It's happening too high on the stack I guess, but that's why it's

The URL there suggests to me that you don't have the SP installed properly
yet. I would start by checking the /Shibboleth.sso/Status or /Session
links as the wiki describes to verify that the script mapping is there and

I don't know what that error page is coming from, but it appears to be an
application issue, and that URL is not meant to be passing through to
application code.

The other point is that the INFO message means you're triggering SSO
across a POST to your application, and if you want that to work, you'll
have to use Apache or something other than Shibboleth.
