Modify the InResponseto value from the IdP before sending the saml response . for testing purpose

I need to modify the InResponseTo value in a testing environment based on a checkbox if it’s checked the IDP would send a modified InResposneT value so that I get an exception.

I’m using .net core

You can use the OnSamlResponseCreated event to update the SAML response.

_samlIdentityProvider.Events.OnSamlResponseCreated += (HttpContext, samlResponse) =>
samlResponse.InResponseTo = “wrong”;

return samlResponse;

return _samlIdentityProvider.SendSsoAsync(userName, attributes);
