WSO2IS + node.js护照-saml集成错误

Question

i'm now trying to test SAML2 integration by using wso2is server and node.js passport-saml module. But it sees not working in wso2 side.

node.js server redirect to wso2 server with SAML assertion. here is decoded SAML request assestion

<?xml version="1.0" encoding="UTF-8"?>
<samlp:AuthnRequest xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol" ID="_e62f87ab1740cab74c67" Version="2.0" IssueInstant="2014-06-16T01:16:54.199Z" ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" AssertionConsumerServiceURL="https://localhost:3000/login/callback" Destination="https://localhost:9443/samlsso">
   <saml:Issuer xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion">passport-saml</saml:Issuer>
   <samlp:RequestedAuthnContext Comparison="exact">
      <saml:AuthnContextClassRef xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion">urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport</saml:AuthnContextClassRef>
   </samlp:RequestedAuthnContext>
   <samlp:NameIDPolicy Format="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress" AllowCreate="true" />
</samlp:AuthnRequest>

after i put user id/password in wso2 log in screen. i got a error

SAML 2.0 based Single Sign-On

Error when processing the authentication request!

Does anybody can give an opinion about this?

in wso2is configuration

SP is registered and i only set up Inbound authentication configuration > SAML2 Web SSO Configuration > Issuer : passport-saml. Assertion consumer URL : http: //localhost:3000/login/callback

Here is node.js code

function findByEmail(email, fn) {
  for (var i = 0, len = users.length; i < len; i++) {
    var user = users[i];
    if (user.email === email) {
      return fn(null, user);
    }
  }
  return fn(null, null);
}

passport.serializeUser(function(user, done) {

additional comment. After i fixed node.js code. passport.use(new SamlStrategy(

  {
    path: '/login/callback',
    entryPoint: 'https://localhost:9443/samlsso',
    issuer: 'passport-saml',
    protocol: 'http://'

It is little weired that, in WSO2is server SAML assertion response.

<saml2:Issuer Format="urn:oasis:names:tc:SAML:2.0:nameid-format:entity">localhost</saml2:Issuer>

I coded Issuer as "passport-saml" but in the SAML response it has been changed to localhost do u have any idea on this?

---

added comment. in SAML Response attribue "Format" was missing in element.

<saml2:NameID>admin</saml2:NameID>

So i changed configuration in WSO2 SAML configuration. I added "NameID format" with "urn:oasis:names:tc:SAML:2.0:nameid-format:entity" After that it seems works. In addition, in SAML response, it doesn't send "email" in SAML response assertion, i did small code change like below. (instead of using email, it uses user id)

passport.use(new SamlStrategy(
  {
    path: '/login/callback',
    entryPoint: 'https://localhost:9443/samlsso',
    issuer: 'passport-saml',

    }
    // asynchronous verification, for effect...
    process.nextTick(function () {
      findByEmail(profile.nameID, function(err, user) {
            console.log('User ',user);
        if (err) {
          return done(err);
        }
        if (!user) {
          // "Auto-registration"
          users.push(profile);
          return done(null, profile);
        }
        return done(null, user);

  }
));

but i still got a error in passport-SAML

Answer 1

I resolved problem. After replace "passport-debug" module to "passport" module, it works full source code is https://github.com/bwcho75/node.js_study/tree/master/WSO2SAML2 enjoy

Answer 2

I can answer the part about why the format attribute was required on the subject name -- it's a bug, which I've filed at https://github.com/bergie/passport-saml/issues/40 .

Glad to hear you got it working!
