## NAME
    [Net::LDAP::Control::NoOp](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3ALDAP%3A%3AControl%3A%3ANoOp/markdown) - LDAPv3 Tree Delete control object

## SYNOPSIS
     use [Net::LDAP](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3ALDAP/markdown);
     use [Net::LDAP::Control::NoOp](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3ALDAP%3A%3AControl%3A%3ANoOp/markdown);

     $ldap = [Net::LDAP](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3ALDAP/markdown)->new( "ldap.mydomain.eg" );

     $noop = [Net::LDAP::Control::NoOp](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3ALDAP%3A%3AControl%3A%3ANoOp/markdown)->new();

     $msg = $ldap->modify( 'cn=Barbara Jensen, o=University of Michigan, c=US',
                           control  => [ $noop ] );

     die "error: ",$msg->code(),": ",$msg->error()  if ($msg->code());

## DESCRIPTION
    "[Net::LDAP::Control::NoOp](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3ALDAP%3A%3AControl%3A%3ANoOp/markdown)" provides an interface for the creation and manipulation of objects
    that represent the "No-Op" control as described by draft-zeilenga-ldap-noop-01.txt
    <<https://tools.ietf.org/html/draft-zeilenga-ldap-noop-01>>.

    The control, which has no corresponding response control, is appropriate for all LDAP update
    requests, including add, delete, modify, and moddn.

    Its criticality is always "TRUE"; it has no value.

    The presence of the "No-Op" control in an operation request message disables the normal effect
    of the operation; i.e. the server will do all processing necessary to perform the operation but
    not actually update the directory.

## CONSTRUCTOR ARGUMENTS
    Since the "NoOp" control does not have any values, only the constructor arguments described in
    [Net::LDAP::Control](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3ALDAP%3A%3AControl/markdown) are supported

## METHODS
    As there are no additional values in the control, only the methods in [Net::LDAP::Control](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3ALDAP%3A%3AControl/markdown) are
    available for "[Net::LDAP::Control::NoOp](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3ALDAP%3A%3AControl%3A%3ANoOp/markdown)" objects.
