2464732 - SAML 2.0 authentication for SP on AS ABAP fails due to required authentication context


You encounter errors during authentication with SAML 2.0 on the Service Provider for AS ABAP

Please check if the trusted provider is configured to require "unspecified" Authentication Context. This can be seen in the trace:
         Authentication contexts
            authentication context: unspecified

And also in the configuration through transaction SAML2 -> Trusted Providers -> choose the relevant Trusted Provider ->  Authentication Requirements

The solution from that note only applies if Authentication Context is set to "unspecified" there.
