# 2.3.  Sync State Control
#
#    The Sync State Control is an LDAP Control [RFC4511] where the
#    controlType is the object identifier 1.3.6.1.4.1.4203.1.9.1.2 and the
#    controlValue, an OCTET STRING, contains a BER-encoded syncStateValue.
#    The criticality is FALSE.
#
#       syncStateValue ::= SEQUENCE {
#           state ENUMERATED {
#               present (0),
#               add (1),
#               modify (2),
#               delete (3)
#           },
#           entryUUID syncUUID,
#           cookie    syncCookie OPTIONAL
#       }
#
#    The Sync State Control is only applicable to SearchResultEntry and
#    SearchResultReference Messages.
