[SOLVED] Response doesn't have any valid assertion which would pass subject validation

I am completely new to SAML, and ADFS. I tried googling my error, but sadly did not get any hits. I have been trying to set up Spring SAML and ADFS so I can get single sign-on working, by following this guide It seems like I am close to the end but I am met by the following error: Response doesn't have any valid assertion which would pass subject validation

Error message: (reformatted for readability)

I checked out the code, and it is supposed to get the assertion from the response (ADFS) and if this is null it throws out the errors. I guess that means my ADFS is missing something, or am I misunderstanding what Assertions are?
