Question
Is it possible to use the Security Assertion Markup Language (SAML) 2.0 Profile for OAuth 2.0 Client Authentication and Authorization Grants?

We have a FrontEnd application integrated through OAuth2 OpenIDConnect to our WSO2 IdentityServer, then we federate all our customers via WSO2 so each customer can opt for their preferred SSO protocol, what I'm looking for is to accept a SAML IdP initiated flow and this could be done using the SAML Bearer over OAuth (as described in the link).

What we were not able to find is a way to start all the flow with your library, but it should be very easy.

Thanks in advance,
