SAP SuccessFactors Integration with OAuth2SAMLBearerAssertion flow.

Abstract.

This authorization flow allows for propagation of a user’s identity from any client application deployed anywhere all the way through to the asset management service (like SAP SuccessFactors in this instance).

A truly end to end Single Sign On!

Putting it all together.

I divided the SAP SuccessFactors Integration with OAuth2SAMLBearerAssertion authorization flow into the following two categories, namely:

1. SAP SuccessFactors Integration with SAP BTP Destination service comprised of three instalments, namely:

a. with the default [destination service] trust OAuth2SAMLBearerAssertion Flow with SAP BTP Destination Service. SAP SuccessFactors.

b. bring your own trust: OAuth2SAMLBearerAssertion flow with SuccessFactors with Quovadis-SAP destination.

c. Troubleshooting: How to troubleshoot SAP BTP OAuth2SAMLBearerAssertion destination with SuccessFactors?

2. SAP SuccessFactors without additional SAP BTP tie-in with the following instalment, namely:

How to generate SAML bearer assertion token for OAuth2SAMLBearerAssertion flow?

Additionally, when a target resource cannot be hooked to an IdP, I may have found a way to help avoid using a system (technical) user with either the built-in destination service definition or when a saml bearer assertion is generated with custom code.

The approach consists of having a self-issued x509-signed JWT token representing a system user identity as described in the following blog post: Bring your self-made user JWT with Keycloak OIDC.
