OCSP request responds 'unauthorized'

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Get a comodo S/MIME certificate
2. Send OCSP request
3. Check in Wireshark and view that the serialNumber differs:

Openssl binary
serialNumber : 0x00aa67d5bb73bf2af0cc7034aac1159283

The serial number the nemid library sends is:
serialNumber : 0xaa67d5bb73bf2af0cc7034aac1159283

Editing d2i in Ocsp.php actually "fixes" the issue, by padding two zeros.
    private function d2i($d)
    {
        $der = '';
        $dd = $d;
        while ($d) {
            $der .= chr(bcmod($d, 256));
            $d = bcdiv($d, 256, 0);
        }
 $der = $der . chr(bcmod(0,256)). chr(bcmod(0, 256)) ;
        return "\x02" . $this->len($der) . strrev($der);
    }
