Creates a container (MS-ShareMapConfiguration)
Grants the DPM server permissions to change the contents of the container
Adds mappings between source shares and shares on the replicas
This appendix describes the classes and attributes that Data Protection Manager (DPM) adds to Active Directory to support end-user recovery.
