NAME

       Net::LDAP::Control::EntryChange - LDAPv3 Entry Change Notification control object

SYNOPSIS

	use Net::LDAP;
	use Net::LDAP::Control::PersistentSearch;
	use Net::LDAP::Constant qw(LDAP_CONTROL_ENTRYCHANGE);

	$ldap = Net::LDAP->new( "ldap.mydomain.eg" );

	$persist = Net::LDAP::Control::PersistentSearch->new( changeTypes => 15,
							      changesOnly => 1,
							      returnECs => 1 );

	$srch = $ldap->search( base	=> "cn=People,dc=mydomain,dc=eg",
			       filter	=> "(objectClass=person)",
			       callback => &process_entry, # call for each entry
			       control	=> [ $persist ] );

	die "error: ",$srch->code(),": ",$srch->error()  if ($srch->code());

	sub process_entry {
	  my $message = shift;
	  my $entry = shift;
	  my ($control) = $message->control(LDAP_CONTROL_ENTRYCHANGE);

	  print $control->changeType()."	".$entry->dn()."
";
	}

DESCRIPTION

       "Net::LDAP::Control::EntryChange" provides an interface for the creation and manipulation of objects that represent the
       "EntryChangeNotification" control as described by draft-smith-psearch-ldap-01.txt.

CONSTRUCTOR ARGUMENTS

       In addition to the constructor arguments described in Net::LDAP::Control the following are provided.

       changeType
	   An integer value telling the type of LDAP operation that the entry has undergone.  It is one of the following values (which represent
	   the LDAP operations indicated next to them):

	   1 = add
	   2 = delete
	   4 = modify
	   8 = modDN
       previousDN
	   When changeType is 8 (for modDN) this parameter tells the entry's DN before the modDN operation.  In all other cases this value is not
	   defined.

       changeNumber
	   This is the change number according to <draft-good-ldap-changelog-03.txt> assigned by a server for the change.  If a server supports an
	   LDAP Change Log it should include this field.

       Usually you do not need to create a "Net::LDAP::Control::EntryChange" control yourself because it is provided by the server in response to
       an option with the "Net::LDAP::Control::PersistentSearch" control.

METHODS

       As with Net::LDAP::Control each constructor argument described above is also available as a method on the object which will return the
       current value for the attribute if called without an argument, and set a new value for the attribute if called with an argument.
