+        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.
