2.2.6 LDAP DirSync Control

The presence of this LDAP control, with object identifier (OID) (3) 1.2.840.113556.1.4.841, in an LDAP Search request instructs AD DS to retrieve the changes made to objects since a previous search with this control OID was performed.

This extension is defined for AD DS in the Active Directory Technical Specification [MS-ADTS] section 3.1.1.3.4.1.3 ("LDAP_SERVER_DIRSYNC_OID").
