Overview
This article explains what the Response Protocol should be in the IdP-Initiated SSO settings of a SAML connection.
Applies To
- Identity Provider (IDP)
- Single Sign-On (SSO)
- IdP-Initiated SSO
Solution
The Response Protocol setting in the IdP-Initiated SSO tab from the SAML settings should be used to configure the protocol that Auth0 should use when communicating with the application.
- For an OIDC application that is expecting tokens, set the Response Protocol to OpenID Connect, and follow the guidance on how to configure your application to handle this response: Configure IdP-Initiated SAML Sign-on to OIDC Apps
- If the application is expecting a SAML Response, or for example, the SAML2 Web App Addon is configured for the application to route the SAML assertion, set SAML as the Response Protocol.
- If the application is expecting a WS-Federation Assertion, for example, the WS-Fed Web App Addon is configured for the application to route the WS-Fed assertion, set WS-Fed as the Response Protocol.
