Request for authentication flow clarification and feasibility of enabling Two-Factor Authentication

1. User Authentication in Oracle SAAS
   
   Query:
   We need to understand the current user authentication mechanism in the SAAS environment. We understand that work is currently underway to synchronize our corporate Active Directory (AD) with Azure AD, and from there with Oracle Cloud.
   
   We require:
   - Confirmation of the current authentication flow:
   On-premises AD ➝ Azure AD ➝ Oracle Identity Cloud Service (IDCS)
   
   -Description of how users and credentials are synchronized.
   
   -Indicate if any authentication protocol is being used (e.g., SAML 2.0, OAuth 2.0, OIDC, etc.).
   
   -Roles and groups synchronized with IDCS, and how these are assigned to roles in Oracle ERP.
   
   -Reference documentation, if applicable.
