Virtual Directory Information Tree Views - Red Hat DIRECTORY SERVER 8.1 - DEPLOYMENT Deployment Manual

• Classic CoS identifies the template entry by both its DN and the value of one of the target entry's
attributes. Classic CoS can have multiple template entries, including a default CoS template to be
applied to those entries that do not belong to any other CoS template.
Roles and the classic CoS can be used together to provide role-based attributes. These attributes
appear on an entry because it possesses a particular role with an associated CoS template. For
example, use a role-based attribute to set the server look-through limit on a role-by-role basis.

4.4. Virtual Directory Information Tree Views

Directory Server supports a concept for hierarchical navigation and organization of directory
information called virtual directory information tree views or virtual DIT views.
NOTE
Virtual views are not entirely compatible with multiple backends in that the entries to
be returned by the views must reside in the same backend; the search is limited to one
backend.
4.4.1. About Virtual DIT Views
There are two ways to configure the directory namespace:
• A hierarchical directory information tree.
• A flat directory information tree.
The hierarchical DIT is useful for navigating the directory but is cumbersome and time-consuming to
change. A major organizational change to a hierarchical DIT can be an expensive and time-consuming
operation, because it usually involves considerable service disruption. This can usually only be
minimized by performing changes after hours and during periods of low traffic.
The flat DIT, while requiring little to no change, does not provide a convenient way to navigate or
manage the entries in the directory service. A flat DIT also presents many management challenges as
administration becomes more complex without any natural hierarchical groupings.
