We have an inbound SSO site and a non SSO site. Now trying to connect to a third-party vendor who uses SSO for a chrome less login to their platform requires us to have two outbound IDPs. Doing this we get a 500 error. Either we need to use the SSO site which the non SSO users are not able to access or use the non SSO site which everyone has access. Unfortunately, the SSO users do not know their usernames and passwords because they normally do not use it because they are SSO users, and it defeats being SSO. I understand having to authenticate, but it would be nice to recognize both portals to make it seamless by having the ability to have two outbound IDPs. The SSO users will need to do extra steps to make things work. This may be a bit challenging for people with disabilities for the first time.
