title: Error: 'There is not exactly one Assertion' Using ITfoxtech Saml2
body: <p>I am using Itfoxtech SAML 2.0 with .net core. But I am getting error 'There is not exactly one Assertion'.
  Does Itfoxtech with with Oracle Access Manager? Can you give me clarity about the signing and certifications. Do I need to use certificate to get the assession?</p>
