!!! Overview
[{$pagename}] is a [Microsoft Active Directory] [SupportedControl] and is an extended version of the [Directory Synchronization Control] with an [OID] of [1.2.840.113556.1.4.2090] which may be referred to as [LDAP_SERVER_DIRSYNC_EX_OID]


[{$pagename}] [SupportedControl] is used with an LDAP search operation in exactly the same way as the [Directory Synchronization Control] ([LDAP_SERVER_DIRSYNC_OID]) control, except for differences specified below. All ASN.1 structures and the meaning of the fields of those structures are the same.

As with the [Directory Synchronization Control], any attributes can be requested in the search. Only those objects for which these attributes have been created or modified since the time represented by Cookie will be considered for inclusion in the search. However, where the [{$pagename}] control returns only those attributes that have changed, the [{$pagename}] control also returns unchanged attributes when the attribute name in the request is appended with the string ";dirSyncAlwaysReturn".
