Prominent new features of Samba 4.5 include support for the LDAP_SERVER_NOTIFICATION_OID control to the Lightweight Directory Access Protocol (LDAP) directory service protocol, as well as improvements to the KCC component to add sparse network replication support. There’a also DRS Replication support for the Active Directory Domain Controller (AD DC), implementation of Virtual List View (VLV) to page the LDAP directory, two new options, namely ‘–local-online’ and ‘–async-op’ were added to the “samba-tool drs replicate” command, and deleted objects now have linked attributes for Active Directory.
