Real-time sync updates user profiles, groups, and group memberships during sign-in instead of waiting for a scheduled import. You do not have to import all the users in your directory beforehand. Real-time sync also updates user information whenever you load or refresh a user's People page. See Using the Okta People Page for more information. Administrators can change organizational units (OUs), user profile information, and group information in Active Directory (AD) and users are immediately updated.
You must install AD Agent 3.0.9 or later to use real-time sync. See Installing and Configuring the Active Directory Agent for more information.
