Deprecated use of preg_replace

Hello,

As of PHP version 5.5 the “e” option has been deprecated when using preg_replace(). When running on a server using PHP 5.5+ with errors on you are shown the following error when trying to login, which also kills the cookies and prevent success.

Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in plugins\active-directory-integration\ad_ldap\adLDAP.php on line 2580

As you can see the error is coming from the ldap_slashes method. Here is a version of the same method that I re-wrote to work with the latest PHP.

protected function ldap_slashes( $str ){
	    $formatted = preg_replace_callback(
		    '/([\x00-\x1F\*\(\)\\\\])/',
		    function( $matches ){
			    return "\\" . join( "", unpack( "H2", "$matches[1]" ) );
		    },
		    $str
	    );

	    return $formatted;
    }

I am currently unable to reach you bug tracking site, so I figured I would post this here.
