During synchronization from target to source user attributes are not being updated (4258581)

Synchronization is configured as two-way synchronization.  
New objects are being created in a specific OU in target domain and sync job is supposed to create these objects in source domain and synchronize them.

DSA creates new objects successfully, however it has been noticed that changes on target are not being synchronized to source and objects in source remain unchanged.

DSA stops synchronizing such objects after they have been created and subsequent changes are not being synchronized.

The issue described above might occur  when new objects are being created in target domain manually and then synchronized by QMM to source domain and created in source   domain in a separate OU which does not participate in synchronization from source to target.   Even if by design it has been confirmed that this is a limitation of the tool.

WORKAROUND:
In order for synchronization to work as expected Quest recommends including the source OU into the synchronization scope from source to target domain.
