This illustration (oimig002) shows a directory information tree (DIT) in Oracle Internet Directory and corresponding multiple domains in Microsoft Active Directory. The DIT in Oracle Internet Directory extends downward from the root DSE to dc=com to dc=MyCompany to dc=us. From there it divides into two branches: dc=a and dc=b. The node dc=a extends to users, and, similarly, the node dc=b extends to users. The multiple domains in Microsoft Active Directory has us.MyCompany.com as the root. From there it extends downward to a.us.MyCompany.com and b.us.MyCompany.com. Each of the latter two nodes extends downward to a node labeled users.
