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 $control->changeType()."\t".$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.
