When using this synchronization type, changes in the Active Directory structure are carried over into your System Tree structure at the next synchronization. When systems or containers are added, moved, or removed in Active Directory, they are added, moved, or removed in the corresponding locations of the System Tree.
When to use this synchronization type
Use this to ensure that the System Tree (or parts of it) look exactly like your Active Directory structure.
If the organization of Active Directory meets your security management needs and you want the System Tree to continue to look like the mapped Active Directory structure, use this synchronization type with subsequent synchronization.
