I can't find a way to get the signed in user's claims when using SAML SSO with the IdP and IdPReact modules. The "GetCurrentClaims" action in IdPReact apparently calls "GetCurrentUserCustomClaims" in the IdP module. That last one was simply "GetCurrentUserClaims" in an earlier IdP version and worked seamlessly. Anybody knows if this is an update, and, if so, how one gets the claims?
So, turns out to be a bug...
Right before the call to "ProcessClaims" in "Saml_Response_Process", I had to add an aggregate:
And pass it to the Config_UserMappings argument in ProcessClaims:
And it solved the problem.
