Optional Implementation

The following features are optional, but highly recommended.

• The IDirectorySearch interface for non-Automation clients. Because the ADSI OLE DB provider uses IDirectorySearch to present queries and collect results from the underlying directory service, providers that implement this interface gain access to OLE DB style databases for no extra effort.
• The IADsSecurityDescriptor, IADsAccessControlList, and IADsAccessControlEntry interfaces. Providers for directory services that support ACL-based object security are strongly encouraged to implement this additional functionality.
