How does data sync between the AD Sync Component and my Windows directory on Workplace?
This article is only applicable to users of Workplace Essential and Workplace Advanced.
AD Sync does a one-way batch replication of selected users' profile data. The AD Sync Component doesn't write back to your directory service. After you configure it to query AD for the set of users you'd like to give access to Workplace, AD Sync will run on a schedule every three hours to reconcile accounts between AD and Workplace.
