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 ] );

 sub process_entry {

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

   print $control->changeType()."\t".$entry->dn()."\n";

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-03.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.
