This illustration shows a directory information tree (DIT) in the Oracle back-end directory and a corresponding forest in Microsoft Active Directory. The DIT in the Oracle back-end directory extends downward from the root DSE to a node labeled Mapping Base to dc=com to dc=MyCompany. From there it divides into two branches: dc=us and dc=uk. The node dc=us extends downward in two branches: dc=a and dc=b. The dc=b node extends downward to dc=c. The node dc=b extends to dc=c. The node dc=uk extends downward to dc=b and then to dc=c. The forest in Microsoft Active Directory has two roots: and The node divides into two branches: and The latter node extends downward to The node extends downward to and from there to
