I need to implement an Identity provider service (using node.js) that should be able to.
Get, validate and parse (using private key and cretificate) the authentication request from SP example
If everything is valid, respond with a signed XML response example
Is there a tool in node.js that can handle the IdP side of SAML protocol. i'm familiar with samlify, saml2, passport-saml, and all of them seem to handle the Service provider side of the protocol.
If the packages mentioned here can serve to my needs, could you specify how exactly they handle this.
Any other directions and/or hints may be helpful.
Thanks
This is what my research say about this modules .
Passport-saml - Provider service provider only
Saml2-js - Provide service provider
Samlify - Idp in experimental phase , You can check idp implementation here. https://github.com/tngan/samlify/blob/f2b6a2f8c36dc0ff887d0442c48cd0f2c0a4a778/examples
Node-samlp - IDP which provide saml assertion but user authorization we need to do our own
Saml-idp - It says IDP we can create but again it refer to online IDP
I have used samlify to make my existing node js application as identity provider to third party service provider.
It has many configuration options. Intially it took time to successfully implement.

The document corresponding to Istio End User Authentication states that
If jwksUri isn’t set, make sure the JWT issuer is of url format and url + /.well-known/openid-configuration can be opened in browser,
End User Authentication Istio
I want to build a JWT Server which serve this requirement for Istio, and can be used as a centralized Authentication Server(SSO) for my micro service based architecture.
Putting it simply, i want to create a centralized JWT issuer which i can use with Istio, kindly refer some resources that i can go through to achieve the same.
you can also refer the link below to have some understanding of my requirement, its same
Central JWT authentication / authorization service
I just want to know how to create JWT Issuer, which can work with Istio, by simply passing the jwksUri as described in the document for Istio End User Authentication
Example
jwksUri: "https://www.googleapis.com/service_accounts/v1/jwk/628645741881-noabiu23f5a8m8ovd8ucv698lj78vv0l#developer.gserviceaccount.com"
To create a centralized authentification server yourself is a long and error-prone process that you can avoid by using an open source solution, like Keycloak or IdentityServer.
An example of using KeyCloak with Istio can be found in the RedHat Istio Tutorial.
You can also use an Authentification as a Service like Auth0, Okta, Azure B2C etc, and all of those are OpenId Connect Conformant (list of conformant services)
Am experimenting SAML 2.0 SSO from a java web application using Azure AD as IDP.
I modified the sample - https://github.com/Azure-Samples/active-directory-java-webapp-openidconnect
to generate a SAML request.
But am getting the below error -
AADSTS75005: The request is not a valid Saml2 protocol message
I tried using OpenSAML library to generate SAML Request.
I would like to know if ADAL4J supports SAML 2.0. If yes, can someone share a sample?
Thanks in advance.
ADAL is a wrapper around a protocol.
Currently, that protocol is OpenID Connect / OAuth.
You need a client side SAML stack.
A lot of Java applications use Spring security.
I think I faced the same or similar problem, and I've found that I am receiving response from custom identity provider in SAML1.1 standard, but ADAL4J recognizes it as SAML2.0 . What I had to do is use modified library, with changed implementation of method isTokenSaml2() in WSTrustResponse class (I've added a lot of additional logging in ADAL4J too). Token type extracted from response was other than expected - "urn:oasis:names:tc:SAML:1.0:assertion"
I want to implement login and logout functionality and retrive user details like username and user role using Azure Active Directory.
We are using Docker to deploy Spring cloud microservices project on Azure cloud. Could you please suggest me steps to get user details?
Do we need to secure all microservices edge points using Spring cloud OAuth2 security using JWT or just we can secure one web microservice ? Do I need any permission ,specific user roles to implement this?
You can find Azure's documentation about OAuth 2.0 support for AAD here
https://learn.microsoft.com/en-us/azure/active-directory/active-directory-protocols-oauth-code
I've got an application that's using OAuth 2.0 with a different Authentication Server, and I'm about to see if I can use AAD as the Authentication Server. But, whatever ends up being your Auth Server, the rest of the application should be the same...
The Auth Server handles the log in (typically as a Single-Sign On pattern)
The Auth Server will return a Json Web Token (at some point, depending on the Grant Type being used to retrieve it)
The JWT should be included in each subsequent request to ensure the caller has authorization
From a Spring perspective, you'll need at least a SSO Client (denoted by the #EnableOAuthSSO annotation). If everything in hosted by that process, you'll need that JWT to call subsequent methods. If you have processes hosted in other processes, it's likely you'll want them secured as well. Using the #EnableResourceServer annotation will configure Spring Security to look for the JWT, just not attempt to retrieve one if the request does not have it.
Unless the endpoint is meant to be publicly accessible, you will want to secure it. Of course, I really don't know the context of your application, so this statement is purely an uninformed opinion based on zero knowledge of what you're trying to do with your application. Take it for what it's worth.
EDIT
This has become a little more complex than I originally thought. I have been able to write some code to dynamically retrieve the public key from Microsoft in order to validate the returned JWT.
But, the main issue is the fact the Azure AD supports Open Id Connect when acting as an Identity/Authentication Server. And, at the moment, spring-security-oauth2 doesn't support Open Id Connect.
I was able to make some small changes to the spring code, but I did ask the question to the Spring group and they are actively working on adding support for Open Id Connect. They hope to have a release two months (ish?).
For the short term, the oauth2 support doesn't support Open Id Connect. Given this is the protocol used by AAD, the current version of oauth2 won't work with AAD. That said, I will be happy to wait for the official support which shouldn't be too long.
I'd like to preface this by saying that until now, I hadn't even HEARD of SAML, much less developed a SSO strategy involving it. That, combined with the fact that I've barely been doing node for a year makes for a glorious newbie sandwich. Currently, I have a client who uses SAML and ADFS as their SSO provider. I am already using passport.js for local logins, so using passport-saml seems to be the way to go to implement the SSO using SAML/ADFS. In doing my research, I've found a couple different implementation guides, but since I literally know NOTHING about this process, I could use a few pointers.
In the passport-saml documentation, I found the following for a strategy proven to work with ADFS (according to the docs):
{
entryPoint: 'https://ad.example.net/adfs/ls/',
issuer: 'https://your-app.example.net/login/callback',
callbackUrl: 'https://your-app.example.net/login/callback',
cert: 'MIICizCCAfQCCQCY8tKaMc0BMjANBgkqh ... W==',
identifierFormat: null
}
I suppose my main question is where does this cert come from? Is this a cert I generate on my server via SSL? Does the provider provide it?
In my searching, I have also found this: https://github.com/auth0/passport-wsfed-saml2, which is based on passport-saml. The following configuration is suggested for ADFS:
{
path: '/login/callback',
realm: 'urn:node:app',
homeRealm: '', // optionally specify an identity provider
identityProviderUrl: 'https://auth10-dev.accesscontrol.windows.net/v2/wsfederation',
cert: 'MIIDFjCCAf6gAwIBAgIQDRRprj9lv5 ... ='
}
In this example, the path object is obvious, and my provider has already given me an providerURL. But realm makes no sense to me, and there's that darn cert again.
Could someone provide me with an "explain-like-i'm-five" way of implementing SAML/ADFS SSO in a node.js site? Or help me make heads or tails of the argument objects requested by the two solutions I've outlined? Much appreciated in advance!
I recently went through the same thought process: having never heard of SAML, I needed to enable a web application to authenticate via SAML with OneLogin as the identity provider (instead of Active Directory).
During implementation, I made heavy use of OneLogin's documentation and the passport-saml library, both of which I recommend, though I'm not affiliated with either.
What I came to realize was that the confusion was three-fold:
(1) how SAML works,
(2) how the passport-saml library works in Node, and
(3) how to configure the identity provider (OneLogin, Active Directory, or otherwise). What follows is my attempt at an "explain-like-I'm-five" explanation.
SAML
Security Assertion Markup Language (SAML) is an XML standard that allows users to log in based on their browser session. There's a lot to it, but basically, it enables a simpler authentication process. A user can click a button rather than submit a form with username and password.
The way SAML works is a little more involved. I found this overview from OneLogin and the accompanying diagram helpful:
The diagram represents the following process:
User clicks a button to authenticate for a given application (sometimes called service provider) using SAML. A request is made (to Node or otherwise) to build a SAML authorization request.
An authorization request is constructed. This authorization request is XML (see more on OneLogin), encoded and/or encrypted, and appended to a URL as a query param. Node redirects the browser to this URL (something like https://domain.onelogin.com/trust/saml2/http-post/sso/123456?SAMLRequest=...encodedXML...).
OneLogin, as identity provider, determines from the browser session whether the user is already logged in. If not, the user is prompted with OneLogin's login form. If so, the browser POSTs a SAML response back to the application (service provider). This SAML response (again XML) includes certain properties about the user, like NameID.
Back in Node, the application verifies the SAML response and completes authentication.
Node and passport-saml
Passport.js is authentication middleware for Node. It requires a strategy, which could be something like passport-local or, in our case, passport-saml.
As the passport-local strategy enables Passport authentication using username/password, the passport-saml strategy enables Passport authentication using the browser session and configurable identity provider values.
While passport-saml served my purposes really well, its docs were difficult to reason through. The configuration example doesn't work due since the OpenIdp identity provider is inactive and there are lots of configurable parameters.
The main one I cared about: entryPoint and path (or callbackURL). I only needed these two, which do the following:
entryPoint is the URL to redirect to with the authorization request (see #2 above).
path/callbackURL set the URL/route in Node for the SAML response to be POSTed to (see #3 above).
There's a ton of other parameters that are important and valuable, but it's possible to configure SAML SSO using just these two.
Identity Provider configuration
Finally, the identity provider itself needs to be configured so that, given a SAML authorization request, it knows where to send the SAML response. In the case of OneLogin, that means setting an ACS (Consumer) URL and an ACS (Consumer) URL Validator, both of which should match the path/callbackURL configured for passport-saml.
Other things can be configured (to support logout and other features), but this is the bare minimum to authenticate.
Summary
There were two parts to the original question: (1) how to implement SAML/ADFS integration and (2) high-level SAML node.js implementation guide. This answer addresses the second.
As for specifically integrating with Active Directory, I recommend passport-saml's docs on ADFS, keeping in mind that there's two parts: configuring passport-saml to use an ADFS identity provider AND configuring your ADFS server to respond back to Node.
I could be wrong here but I believe it comes from the ADFS servers XML found at https://servername/FederationMetadata/2007-06/FederationMetadata.xml.
Pull out the X509Certificate. I have the same issues going on and I'm going to try that next.
As for the first part of your question, the certificate comes from the provider. Please have a look at the passport-saml documentation.
Simply pull out the Identity Provider's public signing certificate (X.509) and make sure to format it to the PEM encoding. The correctly formatted PEM-encoded certificate will begin with -----BEGIN CERTIFICATE----- and end with -----END CERTIFICATE-----.
I have a Drupal site I am standing up for a client.
I've been asked to use Single Sign on using SAML2 (where I would be the service provider and my client would be the identity provider).
The best thing I have found so far has been either
SimpleSAMLPHP https://ow.feide.no/simplesamlphp:drupal
or
Shibboleth -- http://drupal.org/project/shib_auth
From looking at the documentation from these it looks like the Shibboleth module might be further ahead, but I'm not sure that you can connect Shibboleth to SAML. Can you? Or do you need to connect to a Shibboleth identity provider?
The SimpleSAML module looks good, except it seems to require memcache which I would prefer to not use.
Thanks!
The Shibboleth project is an implementation of SAML, which is a specification of a protocol that deals with exchange of Assertions (AKA security tokens). A shibboleth server is an installation that talks the Identity Provider side of the SAML protocol, and it will be able to talk to any Service Provider as long at they both follow the specifications of SAML. Since this is the case for both SimpleSAMLPHP and the Shibboleth Service Provider modules, you can use either really. So if you don't want to use memcache you can safely choose shib_auth.
