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 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.
I am trying to implement SAML 2.0 in my project(c#). I researched and found the work flow. However I am a little confused with the steps from a coding perspective. Please help
SAML is not a simple protocol.
I suggest you use a SAML client side stack. There are some recommendations - refer SAML : SAML connectivity / toolkit.
Can I use spring-security-rest as a replacement of Oauth?. My app has server side part and java script client side part where I found that spring-security-rest plugin fits most. But I want to be able to authenticate other apps who want to consume my service (I want to be something like Oauth provider). Does spring-security-rest plugin support this? or should I use another plugin?
The plugin is not a fully OAuth provider. Or said in OAuth terminology, is not a full Authorisation Server.
In that case I recommend you Spring Security OAuth 2 Provider Plugin
If you are looking only for a simplistic token based authentication for your service, you could leverage the spring security rest plugin and tweak it a little bit based on your need without having to implement the full blown Spring Security OAuth2 Provider plugin. I managed to accomplish something similar with by extending some of the base classes of spring security rest plugin to modify the login payload and authentication and exposed a token/validate as a REST endpoint. I put up this as an independent authentication service that uses the /api/login API for token generation in tandem with the /token/validate to accomplish some kind of validation on token. Not a full blown Oauth scenario but serves the purpose of authentication between consumer and provider services.
I need to implement OAuth 2.0 protocol and I am thinking about "Authorization Server" part. Can I implement it as a custom Security Token Service (based on WIF classes)?
No, the WIF classes don't support the OAuth2 framework. Writing one from scratch is not trivial. The Thinktecture AuthorizationServer is an open source OAuth2 implementation that might get you started:

I'm doing a sample webapp that authenticates against WSO2 Identity Server through SAML. It works fine but now I wanted to retrieve user attributes and roles for authorization and I'm completely lost.
Reading some SAML docs I know that I must send an AttributeQuery request but not how and I've made up that I should use a SOAP request but I don´t know how the server works. I don´t know if WSO2-IS offers a web service or other method. If yes, which would be the wsdl URL to generate the client? And if not, which method should I follow. It could be also possible that the same authentication response includes the user attributes.
Thank you for your help and sorry if the solution is obvious. I haven't found anything about this in your docs and I'm not familiar with security enviromnents and I don´t understand all the options the admin console shows.
While attribute request can be sent to get the details of one or more user attributes, you can get all the information through one call (authentication request) - all the attributes of the user (attributes in the default profile) and the roles of the user.
There is a basic demo application available.
To get attributes, you should use WSO2 4.0 M8 release (which supports the attribute profile).
Once a Service Provider is registered, we can select the required attributes that should be returned. More information about this and the link to get the WSO2 4.0 M8 release can be got from the comment section of "SAML2.0 SSO with the WSO2 Identity Server".
This article provides a detailed description to get user details after SAML Authentication
