When a subordinate data view is created, Directory Proxy Server automatically excludes the subordinate data view from the superior data view. When a request targets the subordinate data view, the request is sent to the subordinate data view instead of the superior data view.
By default, Directory Proxy Server automatically configures the excluded-subtrees parameter in the superior data view to exclude subordinate data views. For information about how to disable the automatic configuration, see To Manually Configure the excluded-subtrees and alternate-search-base-dn Properties in Sun Directory Server Enterprise Edition 7.0 Administration Guide.
The following subtrees are excluded by default from all data views: cn=config, cn=monitor, and cn=proxy manager.
