ShowDeletedControl	The ShowDeletedControl class is used with SearchRequest to specify that the search results should include any deleted objects that match the search filter.
SortKey	The SortKey class stores sort criteria for use by sort controls.

DereferenceAlias	The DereferenceAlias enumeration specifies the process by which aliases are dereferenced.
DirectoryAttributeOperation	The DirectoryAttributeOperation enumeration specifies the operation to perform on a directory attribute.
DirectorySynchronizationOptions	The DirectorySynchronizationOptions enumeration specifies the behavior of the search in a DirSyncRequestControl object.
ExtendedDNFlag	The ExtendedDNFlag enumeration specifies the format of an extended distinguished name.
LocatorFlags	The LocatorFlags enumeration specifies data required to locate a domain controller.

Delegates

DereferenceConnectionCallback	The DereferenceConnectionCallback delegate dereferences a connection that is no longer required. The connection was probably established through a successful call to the QueryForConnectionCallback or NotifyOfNewConnectionCallback delegate.
NotifyOfNewConnectionCallback	The NotifyOfNewConnectionCallback delegate is called if a new connection was created while chasing a referral.
QueryClientCertificateCallback	The QueryClientCertificateCallback delegate gets or sets the default callback function used to specify the client certificates while establishing an SSL connection.
QueryForConnectionCallback	The QueryForConnectionCallback delegate determines whether there is a cached connection available for use.
VerifyServerCertificateCallback	The VerifyServerCertificateCallback delegate gets or sets the default callback function used to verify server certificates when establishing an SSL connection.
