Net::LDAP::Control::EntryChange(3)   User Contributed Perl Documentation  Net::LDAP::Control::EntryChange(3)



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 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.
