Figure 4-11 A combined DIT using views
The DIT Figure 4-11 “A combined DIT using views” in illustrates what happens when the two
DITs shown in Figure 4-10 “Examples of a flat and an organizationally-based DIT” are combined
using views. Because views inherently allow entries to appear in more than one place in a view
hierarchy, this feature has been used to expand the ou=Sales entry to enable viewing the Sales
entries either by location or by product.
Given a set of virtual DIT view hierarchies, a directory user can use the view that makes the most
sense to navigate to the required entries. For example, if the target entries were those who live
in Mountain View, a view which begins by navigating using location-based information is most
appropriate. If it were an organizational question, the organization view would be a better choice.
Both of these views exist in the Directory Server at the same time and operate on the same entries;
the different views just have different objectives when displaying their version of the directory
structure.
The entries in the views-enabled directory in Figure 4-11 “A combined DIT using views” are
contained in a flat namespace just below the parent of the top-most view in the hierarchy. This
is not required. The entries can exist in a hierarchy of their own. The only concern that a view
has about the placement of an entry is that it must be a descendant of the parent of the view
hierarchy.
