        It is absolutely necessary that the parameter ouX509IssuerName is set. It contains
        the base64 encoded certificate, which is DER encoded. The XMLSec needs it to find
        the private key. Although issuer name and certificate should be sufficient to identify
        the certificate the implementation in XMLSec is broken, both for Windows and mozilla.
        The reason is that they use functions to find the certificate which take as parameter
        the DER encoded ASN.1 issuer name. The issuer name is a DName, where most attributes
        are of type DirectoryName, which is a choice of 5 string types. This information is
        not contained in the issuer string and while it is converted to the ASN.1 name the
        conversion function must assume a particular type, which is often wrong. For example,
        the Windows function CertStrToName will use a T.61 string if the string does not contain
        special characters. So if the certificate uses simple characters but encodes the
        issuer attributes in Utf8, then CertStrToName will use T.61. The resulting DER encoded
        ASN.1 name now contains different bytes which indicate the string type. The functions
        for finding the certificate apparently use memcmp - hence they fail to find the
        certificate.
