=head1 NAME

Net::LDAP::Control::SortResult - Server Side Sort (SSS) result control object

=head1 SYNOPSIS

 use Net::LDAP::Control::Sort;
 use Net::LDAP::Constant qw(LDAP_CONTROL_SORTRESULT);
 use Net::LDAP::Util qw(ldap_error_name);

 $sort = Net::LDAP::Control::Sort->new(
   order => "cn -age"
 );

 $mesg = $ldap->search( @args, control => [ $sort ]);

 ($resp) = $mesg->control( LDAP_CONTROL_SORTRESULT );

 if ($resp) {
   if ($resp->result) {
     my $attr = $resp->attr;
     print "Problem sorting, ",ldap_error_name($resp->result);
     print " ($attr)"  if $attr;
     print "\n";
   }
   else {
     print "Results are sorted\n";
   }
 }
 else {
   print "Server does not support sorting\n";
 }

=head1 DESCRIPTION

C<Net::LDAP::Control::SortResult> is a sub-class of
L<Net::LDAP::Control>.  It provides a class for
manipulating the LDAP sort request control C<1.2.840.113556.1.4.474>
as defined in RFC-2891

A sort result control will be returned by the server in response to
a search with a Server Side Sort control. If a sort result control is
not returned then the user may assume that the server does not support
sorting and the results are not sorted.

=head1 CONSTRUCTOR ARGUMENTS

=over 4

=item attr

If C<result> indicates that there was a problem with sorting and that problem was
due to one of the attributes specified in the sort control. C<attr> is set to
the name of the attribute causing the problem.

=item result

This is the result code that describes if the sort operation was successful. If will
be one of the result codes describes below.

=back


=head1 METHODS

As with L<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.

=head1 RESULT CODES

Possible results from a sort request are listed below. See L<Net::LDAP::Constant> for
a definition of each.
