Hi @Ttech , the application you are configuring does not require both the SAML response and the SAML assertion to be signed together. When you choose "Sign SAML response", only the SAML response is signed, and when you choose "Sign SAML assertion", only the SAML assertion is signed.
Please let me know if you have any questions and I can help you further.
