If you want to test your Identifier First with SAML integration, you can use Auth0 to do that. With user/pw authentication, the app is the service provider (SP) and Auth0 is the identity provider (IdP). The gist is there are two models here.
- Your app (SP) <-> Auth0 (IdP)
- Auth0 (SP) <-> Auth0 (IdP)
There will be two Auth0 tenants that play out here. One is that connects to your app for authentication and for discovering any SSO integration, and the other provides another authentication like a login screen for e-mail address whose domain is registered to that second tenant.
