Hi list,

Has anyone got unsolicited SSO working with Reward Gateway (RG). Their metadata contains no X.509 certificate [1]
When I try to do IdP initiated SSO [0] I get the errors below in the logs [2]. I don’t get sent to the IdP login screen either, just redirected to the RG site and get an error page. No additions to relying-party.xml have been made for RG.

I would really like a list of reasons to not do IdP initiated at all :-).
