NAME

       Net::LDAP::Control::Paged - LDAPv3 Paged results control object

SYNOPSIS

	use Net::LDAP;
	use Net::LDAP::Control::Paged;
	use Net::LDAP::Constant qw( LDAP_CONTROL_PAGED );

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

	$page = Net::LDAP::Control::Paged->new( size => 100 );

	@args = ( base	   => "cn=subnets,cn=sites,cn=configuration,$BASE_DN",
		  scope    => "subtree",
		  filter   => "(objectClass=subnet)",
		  callback => &process_entry, # Call this sub for each entry
		  control  => [ $page ],
	);

	my $cookie;
	while (1) {
	  # Perform search
	  my $mesg = $ldap->search( @args );

	  # Only continue on LDAP_SUCCESS
	  $mesg->code  and last;

	  # Get cookie from paged control
	  my($resp)  = $mesg->control( LDAP_CONTROL_PAGED )  or last;
	  $cookie    = $resp->cookie;

	  # Only continue if cookie is nonempty (= we're not done)
	  last	if (!defined($cookie) || !length($cookie));

	  # Set cookie in paged control
	  $page->cookie($cookie);
	}

	if (defined($cookie) && (length($cookie)) {
	  # We had an abnormal exit, so let the server know we do not want any more
	  $page->cookie($cookie);
	  $page->size(0);
	  $ldap->search( @args );
	}

DESCRIPTION

       "Net::LDAP::Control::Paged" provides an interface for the creation and manipulation of objects that represent the "pagedResultsControl" as
       described by RFC 2696.

       The control is allowed on LDAP search requests ("search" in Net::LDAP) only.  On other operations it will - depending on the value of the
       parameter "critical" - either be ignored or lead to errors.

CONSTRUCTOR ARGUMENTS

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

       cookie
	   The value to use as the cookie. This is not normally set when an object is created, but is set from the cookie value returned by the
	   server. This associates a search with a previous search, so the server knows to return the page of entries following the entries it
	   returned the previous time.

       size
	   The page size that is required. This is the maximum number of entries that the server will return to the search request.

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.
