In WCF How Can I add SAML 2.0 assertion to SOAP Header?
- by Tone
I'm trying to add the saml 2.0 assertion node from the soap header example below - I came across the samlassertion type in the .net framework but that looks like it is only for saml 1.1.

I've been researching for days and cannot seem to come up with a straightforward way of doing this in WCF. The web service is running on Glassfish and is soap 1.1, I've tried using all the packaged wcf bindings but have not been able to get them to work. I started down the path of using a MessageInspector, and wrote one but then realized there must be a better way, surely WCF provides some way to insert saml 2.0 assertions. I've made the most progress writing a custom binding - i've been able to get the timestamp and signature nodes in the soap header, but cannot for the life of me figure out the saml assertion. Any ideas?
public static System.ServiceModel.Channels.Binding BuildCONNECTCustomBinding()
{
TransportSecurityBindingElement transportSecurityBindingElement = SecurityBindingElement.CreateCertificateOverTransportBindingElement(MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10);
TextMessageEncodingBindingElement textMessageEncodingBindingElement = new TextMessageEncodingBindingElement(MessageVersion.Soap11WSAddressing10, System.Text.Encoding.UTF8);
HttpsTransportBindingElement httpsTransportBindingElement = new HttpsTransportBindingElement();
SecurityTokenReferenceType securityTokenReference = new SecurityTokenReferenceType();
BindingElementCollection bindingElementCollection = new BindingElementCollection();
bindingElementCollection.Add(transportSecurityBindingElement);
bindingElementCollection.Add(textMessageEncodingBindingElement);
bindingElementCollection.Add(httpsTransportBindingElement);
CustomBinding cb = new CustomBinding(bindingElementCollection);
cb.CreateBindingElements();
return cb;
}
