Description:
------------
CN_match does a case sensitive match to compare the name in the certificate with the name specified in the context. It should be a case insensitive match.


Test script:
---------------
<?php
$uri = 'https://ib-groep.nl/';
$hostname = 'ib-groep.nl';
$context = stream_context_create(array(
    'ssl' => array(
        'verify_peer' => TRUE,
        'allow_self_signed' => FALSE,
        'cafile' => '/etc/pki/tls/certs/ca-bundle.trust.crt',
        'CN_match' => $hostname
    )
));
$web_content = file_get_contents($uri, FALSE, $context);
?>

Expected result:
----------------
The script should not throw any warning and fill $web_content with the data from the website.

Actual result:
--------------
PHP Warning:  file_get_contents(): Peer certificate CN=`IB-Groep.nl' did not match expected CN=`ib-groep.nl' in /home/fkooman/test.php on line 20
