[satosa-users] Exposing SAML 2.0 IdP Entity ID in OIDC Frontend

Hello, we've been setting up SATOSA as a proxy that uses the SAML 2.0 backend to authenticate against a SAML federation, and provides authentication via the OpenID Connect frontend. We've successfully managed to map attributes from the SAML side to scopes on the OIDC side. However, to qualify these attributes, it seems sensible to also check the SAML entity ID of the IdP that made the assertions. How can we expose the entity ID of the IdP asserting the identity of the user on the OIDC side?
