SYNOPSIS

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

 $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;

DESCRIPTION

"Net::LDAP::Control::SortResult" is a sub-class of Net::LDAP::Control. It provides a class for manipulating the LDAP sort request control 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.

CONSTRUCTOR ARGUMENTS

attr: If "result" indicates that there was a problem with sorting and that problem was due to one of the attributes specified in the sort control. "attr" is set to the name of the attribute causing the problem.
result: This is the result code that describes if the sort operation was successful. If will be one of the result codes describes below.

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.

RESULT CODES

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

LDAP_SUCCESS
LDAP_OPERATIONS_ERROR
LDAP_TIMELIMIT_EXCEEDED
