title: format of certificate Issuer string in SAML reponse
body: <p>When signing a SAML Assertion with the private key of an SSL certificate, what is the format of the certificate's Issuer string?</p>
  
  <pre><code> Dim ResponseIssuer As XmlElement 
   ResponseIssuer = doc.CreateElement("Issuer", "urn:oasis:names:tc:SAML:2.0:assertion")
   Dim issuerFormat As XmlAttribute
   issuerFormat = doc.CreateAttribute("Format")
   issuerFormat.Value = "urn:oasis:names:tc:SAML:2.0:nameid-format:entity"
   ResponseIssuer.Attributes.Append(issuerFormat)
   ResponseIssuer.InnerText = IssuerString    ' &lt;= here
   &lt;snip&gt;
  </code></pre>
  
  <p>When I examine the Issuer in MMC Certificates snap-in, this is the display in the window's text-area:</p>
  
  <pre><code> CN = DigiCert SHA2 Secure Server CA
   O  = DigiCert Inc
   C = US
  </code></pre>
  
  <p>Copying and pasting that string, including carriage-returns does not seem to work. Is only a particular chunk of it required?</p>
