Works with federated Single Sign-On (SSO) solutions that are compatible with SAML 2.0 as an IdP. This includes Microsoft Active Directory Federation Services (ADFS), Shibboleth Identity Provider, and Oracle Access Management (OAM).
Allows users to log into Oracle Identity Cloud Service using their own credentials from the Identity Provider.
Can force the IdP authentication for all users or offer the IdP authentication as an option (Login Chooser option).
