=head1 NAME

Net::LDAP::Control::DontUseCopy - LDAPv3 Don't Use Copy control object

=head1 SYNOPSIS

 use Net::LDAP;
 use Net::LDAP::Control::DontUseCopy;

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

 $nocopy = Net::LDAP::Control::DontUseCopy->new( critical => 1 );

 $msg = $ldap->search( base => 'o=University of Michigan,c=US',
                       filter => '(cn=Barbara Jensen)'
                       control  => [ $nocopy ] );

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


=head1 DESCRIPTION

C<Net::LDAP::Control::DontUseCopy> provides an interface for the creation
and manipulation of objects that represent the C<DontUseCopy> control as
described by RFC 6171.

It allows the the client to specify that copied information should not be used
in providing the service.

The control is appropriate for LDAP search and compare operations [RFC4511]
and inappropriate for all other oeprations.

Its criticality must be TRUE; it has no value.

There is no corresponding response control.

=head1 CONSTRUCTOR ARGUMENTS

Since the C<DontUseCopy> control does not have any values only the
constructor arguments described in L<Net::LDAP::Control> are
supported

=head1 METHODS

As there are no additional values in the control only the
methods in L<Net::LDAP::Control> are available for
C<Net::LDAP::Control::DontUseCopy> objects.
