I am not sure but is it possible to pass entityId in AuthnStatement to Shibboleth SP? I am already sending uid in response AuthnStatement.
Suppose a request is coming to Idp from SP having entityId as https://sp.example.com/Shibboleth. After authentication, Idp should post uid as well as entityId to SP.
Let me know if this is possible or is there any way to get entityId attribute in IdP attribute-resolver.xml file.
Thanks in Advance.
