You use synchronization settings to control the direction in which object creations, object deletions, passwords and other attribute modifications are propagated between Directory Server and Windows directories. Synchronization flow options are as follows:
From Directory Server to Active directory/Windows NT
From Active directory/Windows NT to Directory Server
Bidirectionally
In a configuration that includes Active Directory and Windows NT, it is not possible to save a configuration that specifies different synchronization settings for creations or modifications between Windows NT and Directory Server, and between Active Directory and Directory Server.
