I need a way to POST a <samlp:response> message to a certain URL, its fairly simple and .NET helps me with Saml2Assertion class but I can't seem to find a way to wrap that assertion in a response and have it serialized (or even send without manual post)?
Saml2Assertion assert = new Saml2Assertion(new Saml2NameIdentifier("SAMLIssuer"));
assert.Subject = new Saml2Subject(new Saml2NameIdentifier("10001", new Uri("urn:oasis:names:tc:SAML:2.0:nameid-format:persistent")));
Saml2AuthenticationContext context = new Saml2AuthenticationContext(new Uri("urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport"));
assert.Statements.Add(new Saml2AuthenticationStatement(context, DateTime.Now));
string assertion;
using (var sw = new StringWriter())
{
var xws = new XmlWriterSettings();
using (var xw = XmlWriter.Create(sw, xws))
{
var handler = new Saml2SecurityTokenHandler();
handler.WriteToken(xw, new Saml2SecurityToken(assert));
}
assertion = sw.ToString();
}
And the XML I get for assert seems fine:
<?xml version="1.0" encoding="utf-16"?>
<Assertion ID="_fc348927-c0bf-4955-b98f-483043d8dedd" IssueInstant="2017-04-19T11:29:38.464Z" Version="2.0" xmlns="urn:oasis:names:tc:SAML:2.0:assertion">
<Issuer>SAMLIssuer</Issuer>
<Subject>
<NameID Format="urn:oasis:names:tc:SAML:2.0:nameid-format:persistent">10001</NameID>
</Subject>
<AuthnStatement AuthnInstant="2017-04-19T11:29:39.040Z">
<AuthnContext>
<AuthnContextClassRef>urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport</AuthnContextClassRef>
</AuthnContext>
</AuthnStatement>
</Assertion>
So, what now? How do I get from my code to getting:
<samlp:Response
xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol"
xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion"
ID="new id"
InResponseTo="old id"
Version="2.0"
IssueInstant="2017-04-19T11:29:39.040Z"
Destination="some url">
<saml:Issuer>SAMLIssuer</saml:Issuer>
<samlp:Status>
<samlp:StatusCode Value="urn:oasis:names:tc:SAML:2.0:status:Success"/>
</samlp:Status>
<saml:Assertion ....
without using external libraries or making my own wrappers/string concatenations? I can't seem to find anything in .NET 4.5 implementation of WIF that can help me.
