## NAME
    [Net::LDAP::Control::MatchedValues](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3ALDAP%3A%3AControl%3A%3AMatchedValues/markdown) - LDAPv3 MatchedValues Control

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

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

     $mv = [Net::LDAP::Control::MatchedValues](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3ALDAP%3A%3AControl%3A%3AMatchedValues/markdown)->new( matchedValues => '((sn=Jensen)(sn=Miller))' );

     # return the entries of all people with first name "Babs",
     # but only show the sn if it is "Jensen" or "Miller"
     my $mesg = $ldap->search( base => "o=University of Michigan, c=US",
                               filter => "(givenName=Babs)",
                               attrs => [ qw/sn/ ],
                               control => $mv );

## DESCRIPTION
    "[Net::LDAP::Control::MatchedValues](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3ALDAP%3A%3AControl%3A%3AMatchedValues/markdown)" provides an interface for the creation and manipulation of
    objects that represent the "MatchedValues Control" as described by RFC 3876.

    The "MatchedValues Control", which only has a meaning with the "Search" operation, allows the
    client to specify criteria that restrict the values of attributes returned. It has no effect on
    the number of objects found, but only allows one to restrict the values of the attributes
    returned by the search to those matching the criteria.

## CONSTRUCTOR ARGUMENTS
    In addition to the constructor arguments described in [Net::LDAP::Control](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3ALDAP%3A%3AControl/markdown) the following are
    provided.

    matchedValues => VALUESRETURNFILTER
        A filter giving the criteria which attribute values shall be returned.

        VALUESRETURNFILTER is a sequence of simple filter items of the form "( <ATTRSPEC> <OP>
        <VALUE> )" surrounded by an additional set of parentheses; e.g.

        ((personsAge<=29))
            Only return the age if is less than 30 ;-)

        ((cn=*Emergency*)(telephoneNumber=+1*)(telephoneNumber=911))
            Only return those values of the cn that contain "Emergency", and phone numbers from
            North America including the one for emergency calls.

## METHODS
    As with [Net::LDAP::Control](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3ALDAP%3A%3AControl/markdown) 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.
