how to create own IDP for SAML in java or node - saml

I want to create a SSO to be used by multiple applications, what would be the best way to do it. I was going through SAML2.0 but I am confused as I didn’t find any articles to create own/custom SAML IDP.
1.How feasible it is to create own IDP.
2.What is the best way to implement SSO

Question 1: How feasible it is to create own IDP?
Answer:
How to build and run Shibboleth SAML IdP and SP using Docker container at GitHub repository provides the instruction on building your own IDP for SAML in Java using Shibboleth SAML IdP and OpenLDAP.
Shibboleth SAML IdP is responsible for identity federation.
OpenLDAP is responsible for identity authentication.
Question 2: What is the best way to implement SSO?
Answer:
Shibboleth IdP has implemented SSO for enterprise applications which have been integrated with SAML SP.
(I) I have validated SAML Single Sign-On (SSO) provided by Docker-running Shibboleth SAML IdP (Identity Provider) and OpenLDAP for the following enterprise applications. In other words, I leveraged Docker-running Shibboleth SAML IdP and OpenLDAP to log in to the following enterprise applications successfully.
Microsoft Office 365
Google G Suite
Salesforce
Dropbox
Box
Amazon AWS
OpenStack
Citrix NetScaler
VMware vCloud Director
Oracle NetSuite
(II) We developed our former version of Zero-Password Authentication and Authorization System in Java and leveraged Shibboleth IdP to provide SAML SSO for enterprise applications.
We developed our current version of Zero-Password Authentication and Authorization System with scalability and high availability in Scala to provide SAML SSO natively for enterprise applications without Shibboleth IdP.
For quick deployment of SAML IdP on your production environment, leveraging third-party SAML IdP (such as Shibboleth IdP) is highly recommended. Then you have sufficient time to develop your own SAML IdP in Java or other programming language.
(III) Another StackOverflow question "How to implement or integrate single sign on with SAML and Shibboleth" provides valuable information and discussions.

Question 1: How feasible it is to create own IDP?
Yes, it is possible but requires lots of efforts.
This repository can help you figuring out how to build your own IDP: A mock IDP and SP using the OpenSAML library
This repository can help you on how to integrate your own IDP to Spring Boot application: Spring Boot, SAML, and Okta
Question 2: What is the best way to implement SSO?
In my oppinion, the best way to implement SSO is using pay-as-go identity service. It helps you saving efforts and money. There are many such services from Amazon, Google, Apple, Okta, Auth0, geetoPod, etc.

Don't try and roll your own - use a supported solution.
On the client side, you need a SAML stack.
Some of these come with an IDP you can install.
Have a look at:
Shibboleth
Azure AD - SAML IDP in the cloud
SaaS e.g. Auth0, Okta - SAML IDP in the cloud
identityserver4 with SAML plugin
ComponentSpace - has both client and server side
Sustainsys - has both client and server side
All of these will provide a SAML IDP.
They also provide good documentation to get you up and running.

How can I simulate an identity providers for SAML?

I'm writing some SSO code, that will allow any IdP that supports SAML to authorize with my code.
I need an IdP Simulator that can provide me a metadata URL with the Idp config so that I can test my code. (I'm providing in my code the SP config).
I search but couldn't find some kind of simulator, all I found were tools that manage the apps if I provide both the IdP and SP configs, which is not what I'm looking for.
Thanks a lot!
SAMLtest.id is a free SAML 2.0 testing service that allows you to test your SAML-compliant Service Provider (which is effectively what you have, based on your description). You need to upload a metadata document representing your SP / your application, and you'll be able to download the SAMLtest metadata to use to form your half of the integration.
This is effectively the new version of TestShib, which shut down a number of months ago due to lack of community support, and I use it relatively regularly.
Good luck!
Alternatively you could also use SSOCircle , which offers a free of charge SAML IdP as well (https://www.ssocircle.com/en/portfolio/publicidp/). E.g. it is configured as a default SAML IdP for Spring Security SAML extension.
(I) How to build and run Shibboleth SAML IdP and SP using Docker container at GitHub repository allows you to build and run a standalone IdP Simulator at your own testbed. Running a standalone SAML IdP Simulator by yourself allows you to test your SP code and debug your SAML SP log by checking server logs of both IdP and your SP developed by you.
(1) Download the source code from How to build and run Shibboleth SAML IdP and SP using Docker container at GitHub repository
git clone https://github.com/winstonhong/Shibboleth-SAML-IdP-and-SP
(2) Copy your SP metadata file into
shibboleth-idp-dockerized/ext-conf/metadata/
(3) Extract IdP metadata file "idp-metadata.xml" from
shibboleth-idp-dockerized/ext-conf/metadata/
and upload it to your SP server developed by you
(4) Follow the README instruction to run OpenLDAP server and SAML IdP server using Docker container
(5) Run your SP server developed by you
(6) Now you can check the server logs of both Shibboleth IdP and your SP server to debug your SP code.
In addition, shibboleth-sp-testapp/ folder provides the reference SP configuration for your SP server developed by you.
(II) Another StackOverflow question Setting up a new Shibboleth IdP to work with an existing SAML SP discusses the SAML configuration between IdP and SP.
(III) TestShib is the online Shibboleth IdP simulator built and run by the Shibboleth community. It is exactly the same as the above standalone Shibboleth IdP simulator built and run by yourself.

Where to test IdP-Initiated SSO?

We've developed a SAML2 SP (supporting IdP-Initiated SSO, as per the user journey we want).
My question is, short of developing an IdP, how can we test it is working? Is there an IdP-Initiated SSO test harness out there? (I know of SSO Circle, but that is for SP-Initiated SSO).
You can use a trial account from Onelogin and configure a SAML Test Connector, or deploy your own IdP with simpleSAMLphp
You can test out IdP-Initiated SSO via this JS Bin: https://output.jsbin.com/nukiso
The code is quite long and wouldn't be appropriate to put directly into this post.
It works completely on the browser side and uses web crypto APIs for signing the assertion. It is probably a better idea to use a real IdP as this is more of a tool for learning how to make the SAML response/assertion. To prevent anyone from being able to log into your website without authentication, do not use the JS Bin IdP metadata on a public/production server.

How to configure WSO2 API Manager to an external Identity Provider?

All,
I'm trying to configure the wso2 product with an external IDP, not the IS IDP. What configuration files need to updated and with what information? Also, when I add an IDP from the API Manager browser, where is that file being saved server-side and is it being used?
Thanks,
Hunter
If your IDP supports saml you can configure it as federated IDP in APIM directly. If your IDP does not support saml , plug wso2 IS between APIM and your IDP and configure your IDP as federated IDP in wso2 IS.
In order to add an external IDP, you can use WSO2 Identity Server to bridge the external IDP to API Manager. I believe this article will be helpful to figure out the design and configuration for you solution. This webinar and related blog to the same, would help too.
I have made wso2 am 1.10.0 work with PingFederate saml2 (with and without IS, now without IS), for the majority of it. How to integrate WSO2 API Manager (AM) 1.10.0 with PingFederate SAML 2.0?.
I followed the instructions here https://docs.wso2.com/display/AM1100/Configuring+Single+Sign-on+with+SAML2 - just assuming WSO2 IS as PingIdentity. For the mojority part it's working, but I cannot generate keys when subscribing to an API. It says "invalid credentials" even if I have logged into applications and subscriptions and can create applications from /store UI.

ADFS Implementation for Internal Applications

We are looking forward to implement ADFS to implement SSO across our organization for various set of web applications such as (SAP, Siebel, Custom java based, Asp.net etc.).
I understand based on my research that ADFS can be used to achieve SSO for third party applications using SAML. It can act as an identity provider for third party applications. Please correct me if I am wrong.
Can we use the ADFS to implement cookie based SSO for the various internal web based apps which I mentioned above?? (For Ex: CA Siteminder, ORacle Access manager can work with almost every internal web based application)
In other words: we have one application using apache webserver, one using IIS webserver, one using IHS webserver; can ADFS be used to achieve Single sign on with all these applications??? If yes, How ???
Thanks in Advance...!!
Ashish
ADFS implements SSO via federation using either WS-Fed or SAML 2.0.
If these applications can support these protocols, then yes just federate these products with ADFS and you will get SSO.
e.g. SalesForce SSO with ADFS.
For Java you need a SAML stack e.g. Spring Security.
For ASP.NET, use OWIN or WIF.

How to use SSO with SAML2.0

we have a web application(Say wA) developed in java and we need to provide SSO login from client web application(Say WB) to WA and the requirement is to do with Okta-(SAML 2.0).
Currently im having the Idp mnetadatak, IDP Single Sign-On URL and Identity Provider Issuer link created from okta
Anybody please help me on this issue , what things to do in my application side to provide SSO login felicity. how to listen SSO request from my APP (WA).
Thanks and regards
In case you would like to add SAML support directly into your application (as opposed to including it for example in reverse proxy such as Apache or IIS), you can use either Spring SAML (with minimal Spring configuration in case you don't use Spring Security already) or OpenAM's Fedlet.
Spring SAML enables applications to act as a SAML 2.0 Service Provider by initializing web single sign-on towards IDP (Okta) and accepting and validating response (SAML 2.0 Assertion) sent back from Okta.
Good approach to implement Spring SAML is to start with the quick start guide which helps you create SAML 2.0 integration with a public SAML 2.0 Identity Provider, then change the IDP to Okta and then integrate the result into your application.
It is also possible to build SAML 2.0 support from scratch (using OpenSAML library), but significant knowledge of the protocol is needed for it to be done securely.
Some application servers also include SAML support (WebLogic, WebSphere, JBoss with its PicketLink library), but such configuration is of course not portable.
