In this scenario, Example.com acquires a new company, Acquisition.com. The new company stores its user data in its own Directory Server. For management purposes, Example.com wants to retain this directory structure. However, certain client applications need to see the use data from Acquisition.com as if it were user data from Example.com.
The following diagram illustrates how the virtual directory provides a virtualized merge of the acquired company's data into the existing directory structure.
Acquisition.com's directory is seen as a separate branch under the ou=people branch. The DNs of the entry's in Acquisition.com's directory are transformed when they are viewed through the virtual directory.
