Explanation

By using Google Cloud Directory Sync, you've already automated the creation and maintenance of users and tied their lifecycle to the users in Active Directory. Although Google Cloud Directory Sync provisions user account details, it doesn't synchronize passwords. Whenever a user needs to authenticate in Google Cloud, the authentication must be delegated back to Active Directory, which is done by using AD FS and the Security Assertion Markup Language (SAML) protocol. This setup ensures that only Active Directory has access to user credentials and is enforcing any existing policies or multi-factor authentication (MFA) mechanisms. Moreover, it establishes a single sign-on experience between your on-premises environment and Google. https://cloud.google.com/architecture/identity/federating-gcp-with-active-directory-configuring-
