You should design OUs for simplicity. Previous chapters emphasized the use of mini mal numbers of forests and domains. However, it is likely that your domains will require a number of OUs to meet administrative requirements. The best practice is to begin with one OU and then add only those OUs that you can justify. Although you can have many levels of nested OUs, keep the number of levels to a minimum (fewer than seven) to avoid administrative and performance problems.

You can find a wide variety of advice on how many levels down an OU structure is acceptable. Three to seven levels are probably the most common recommen dations. However, some suggest that ten levels is still acceptable. The way in which you choose to configure and use the OU structure is probably of more con cern than the actual number of levels. For example, a five-level nested OU struc ture with different group policies applied at each level would actually be more cumbersome than a seven-level OU hierarchy with fewer group policies applied. Logon and startup times increase when the system has more group policies to evaluate. Further, if you set different permissions on each OU in the hierarchy, troubleshooting could be considerably more difficult than if you had a structure with uniform (inherited) permissions applied. The point to keep in mind is to organize the OU structure to minimize the number of changes in permissions and to reduce the number of GPOs processed. When designing OU structures for your organization, it s also important to keep the following in mind:

// Get an EM final EntityManager em = emHook.getEntityManager(); // Make a new "Dave" as a detached object with same primary key, but a different name final SimpleEmployee dave = new SimpleEmployee(ID_DAVE, NAME_DAVE_ NEW); // Merge these changes on the detached instance with the DB em.merge(dave); // Ensure we see the name change Assert.assertEquals("Employee Dave's name should have been changed ", NAME_DAVE_NEW, dave.getName()); longer managed // Now we'll detach Dave from the EM, this makes the object no em.detach(dave); // Change Dave's name again to some dummy value. Because the // detached and no longer managed, we should not see this new value // synchronized with the DB dave.setName("A name we shouldn't see flushed to persistence"); log.info("Changing Dave's name after detached: " + dave); // Return return null;

OUs are not security principals. That is, you cannot assign access permis sions based on a user s membership in an OU. Access control is the respon sibility of global, domain local, or universal groups. Users will not use the OU structure for navigation. Although users can see the OU structure of a domain, the most efficient way for users to find resources in Active Directory is to query the global catalog. Therefore, you should define OUs with administration, not users, in mind.

ing domain. In addition to belonging to any domain groups an administrator has added the trusted domain user to, this user is a member of the Everyone group and the Network group two implicit groups, or groups whose membership is determined by a user s status on the network rather than by explicit placement of the user in a group. Because of the wide access that the Everyone group can potentially have within com puters of the domain especially in down-level operating systems such as Windows NT 4.0 even a user who has not been granted access to resources on a computer in the domain might be able to carry out malicious activities.

The following questions are intended to reinforce key information presented in this lesson. If you are unable to answer a question, review the lesson and then try the ques tion again. Answers to the questions can be found in the Questions and Answers section at the end of this chapter. 1. What are the three reasons for defining an OU

A user from a trusted domain can do anything that the Everyone group can do in the trusting domain. For example, the Everyone group has read access to shares by default in Windows Server 2003 and Full Control in Windows 2000 and Windows NT 4.0. Another point of access is the ability to sit down at a workstation in the trusting domain and log on to the trusted domain.
