Where Layer7 will be your SAML audience defined in the assertion.
Environment
Release: Component: APIESM
Resolution
The gateway is setup to validate SAML assertions it has generated. If the audience does not match the Gateway URL as returned by ${request.url.host} the validation will fail.
Please make sure you are using a valid SAML assertion with a properly defined audience.
