So this thing messes with the data being transmitted. I can see how that would conflict with Shibboleth. Way back at the start, wasn't the question asked "is this a vanilla IIS install"? It seems to me that if you're adding this to it, it's no longer a vanilla IIS install.

Workaround: Don't use "RadCompression".

It might be a good idea to add this to the documentation for the next guy that runs in to it though.
