Because a directory service is (among other things) a specialized database, it should not come as a surprise that some of the most important directory design considerations involve data. It is critical that you put some effort up front into thinking about what kind of information you will store in your directory service and how you will obtain and manage that information.

In this chapter we first examine the major issues surrounding directory data and describe some common data-related problems. We also explain how to define a data policy statement that is appropriate for your deployment. Next we explore some techniques for identifying what data should be stored in your directory service. Then we take a step back and look at some general characteristics of data. Finally, we discuss some potential sources for data and tips for maintaining good relationships with all the data sources that exist within your organization.
