Target AD OU structure is not visible correctly in the CMN Directory Connector Wizard (4350235)

When configuring the Notes to Exchange Connector with the Coexistence Manager for Notes (CMN) Directory Connector, the Target AD OU structure is not visible correctly in the Wizard. Some OUs can be seen, and the OU in which we want to create the Contacts objects is not visible.

Using the ADUC mmc snap-in the Service Account configured in CMN is able to see all the OUs in the Target AD. The AD service account used from the Connector has "Read" permission to the entire AD Domain from the root. And the "Full Control" permission to the Target OU, where the Contacts objects to be created.
