Has anybody run in the issue that ICN directly routes the user to the /error.jsp after loading the ICN url (SAML SP auth)?

Sure. Using PingFederate, ADFS and a third one that for my life I cannot remember.

This has been always a few days of lots of reading and then frustrating debugging. I'm sure error.jsp came up a few times.
But in the end we got it working.
