Re: SourceID.NET --another Server Error in '/idp' Application

I added it toward the bottom, one line up from the end tag - 
configuration based on XML is not the least error-prone thing :-)

The element should begin right below the document root. There shouldn't 
be an existing mscorlib tag to modify or anything like that.

So my last lines of the configuration file are:

  <!-- added by SourceID.NET -->
  <mscorlib>
    <cryptographySettings>
      <cryptoNameMapping>
        <cryptoClasses>
          <cryptoClass 
exc14n="Microsoft.Web.Services.Security.XmlDsigExcC14NTransform, 
Microsoft.Web.Services" />
          <cryptoClass 
exc14n.comments="Microsoft.Web.Services.Security.XmlDsigExcC14NWithCommentsTransform, 
Microsoft.Web.Services" />
        </cryptoClasses>
        <nameEntry name="http://www.w3.org/2001/10/xml-exc-c14n#" 
class="exc14n" />
        <nameEntry 
name="http://www.w3.org/2001/10/xml-exc-c14n#WithComments" 
class="exc14n.comments" />
      </cryptoNameMapping>
    </cryptographySettings>
  </mscorlib>
</configuration>
