Authorizations are transferred from Novell to Microsoft on the basis of the Trustee Information of the appropriate Novell Volume.
Under Novell it is possible not only to assign rights to users and groups but moreover to other projects from the active directory, like organization units. The use of OUs for assigning authorizations is a simple method, as new objects need not be created anymore. Furthermore it is common practice in Novell to create rights directly on the user level.
The Novell Connector of migRaven is in the position to transfer all these rights sensibly in the Microsoft world. Prerequisite: The user accounts have been replicated to Microsoft and have been assigned via the SAM.
