The DIT in Oracle Internet Directory extends downward from the root DSE to dc=com to dc=MyCompany to dc=us to users. From there it extends to four leaves: user_1, user_2, user_3, and user_4. The single domain in Microsoft Active Directory has us.MyCompany.com as the root. From there it extends downward to users, and from there to four leaves: user_1, user_2, user_3, and user_4.
