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

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

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

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

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

     print "Results are sorted\n"  if $resp and !$resp->result;

DESCRIPTION
    "Net::LDAP::Control::Sort" is a sub-class of Net::LDAP::Control. It provides a class for
    manipulating the LDAP Server Side Sort (SSS) request control 1.2.840.113556.1.4.473 as defined
    in RFC-2891

    If the server supports sorting, then the response from a search operation will include a sort
    result control. This control is handled by Net::LDAP::Control::SortResult.

CONSTRUCTOR ARGUMENTS
    order
        A string which defines how entries may be sorted. It consists of multiple directives,
        separated by whitespace. Each directive describes how to sort entries using a single
        attribute. If two entries have identical attributes, then the next directive in the list is
        used.

        Each directive specifies a sorting order as follows

          -attributeType:orderingRule

        The leading "-" is optional, and if present indicates that the sorting order should be
        reversed. "attributeType" is the attribute name to sort by. "orderingRule" is optional and
        indicates the rule to use for the sort and should be valid for the given "attributeType".

        Any one attributeType should only appear once in the sorting list.

        Examples

          "cn"         sort by cn using the default ordering rule for the cn attribute
          "-cn"        sort by cn using the reverse of the default ordering rule
          "age cn"     sort by age first, then by cn using the default ordering rules
          "cn:1.2.3.4" sort by cn using the ordering rule defined as 1.2.3.4

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.
