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


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 $control->changeType()."\t".$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-01.txt.


CONSTRUCTOR ARGUMENTS

In addition to the constructor arguments described in the Net::LDAP::Control manpage 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
  3. = modify
  4. = 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 the Net::LDAP::Control manpage 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.
