I am a beginner for saml authentication. I can understand the concepts and theme. But in real time, I do not know how to implement and code it.
What are all needed? How to code for the saml authentication? What technology needed? How many servers/websites needed? Which will be the service provider and identity provider. I do not know the procedure to code.
What are the prerequisites should i know?
I referred http://docs.oasis-open.org/security/saml/Post2.0/sstc-saml-tech-overview-2.0-cd-02.html#1.Introduction|outline. But it is quite confusing. I could not get a clear idea to implement for my own.
What are the series of instructions to implement SAML authentication
for my own sever/website?
Which will be the IDENTITY provider(Authorization server) and
SERVICE provider?
How websites put it in service provider(Resource server) and saml authentication given?
How credentials stored and token response generated in the identity
provider.
How to implement as a code and what are needed to create?
Please help me.. Thanks in advance...
You haven't specified the language but on the client side, you need a SAML stack.
Refer SAML : SAML connectivity / toolkit.
On the server side, you need an IDP.
This could be ADFS, shibboleth, identityserver or an IDaaS product like Auth0 or Okta.

I'm new in the profesional world, and my boss just asked me to configure on an already existing website an SSO using ADFS ans SAML.
I tried looking online, but I have no idea what to do...
I know how to install ADFS in my AD, and that's it
Thank you for your help and your time
This is very vague question. I doubt you can get a complete solution at one place.
First step will to exchanges the federation metadata between ADFS and your app.
Register your application as the relying party in ADFS. know more.
Consume ADFS federation metadata xml in your app.
Your application must be a SAML Service Provider. Means it must redirect to ADFS for authentication. It must expose the Assertion Consumer URL to ADFS.
Once ADFS provides the assertion, your app must be able to parse and sign-verify it.
There is lot more to it. Best way is to clone the existing SAML projects on GIT and accommodate the source code in your existing app.
I have an internal app that allows users to sign in using Azure AD. On authentication, a SAML assertion is returned. However, some of the calls that the application makes require a JWT. WHat is the best way for me to get a JWT when a user signs in? Or is there a way for me to exchange the SAML for a JWT?
Disclaimer: I'm not expert an any of this stuff; I'm still learning it too and struggling with a similar problem. That said, here is my understanding.
I'm pretty sure there is no connection between SAML and JWT. Not a surprise, given that SAML 2.0 dates back to 2005 and JWT got started around 2012. So it's logically impossible for the SAML spec to say anything about JWTs.
If my understanding is correct, you have two options:
Do not use SAML directly. Instead of interacting with a SAML IdP (identity provider), use OpenID Connect and OAuth 2.0 with a provider that acts as an authentication broker. Configure the broker to act as service provider to your chosen SAML IdP. Configure your application to act as relying party (OAuth terminology, I think?) on the authentication broker. Then your app is OAuth 2.0/OpenID Connect/JWT all the way down. Your only interaction with SAML is configuring an authentication broker. Main downside is now you have to select and pay for an authentication broker as well as a SAML IdP.
Write your own authentication/authorization service to consume SAML assertions and issue JWTs. This might be necessary anyways, depending on how you need to represent authorization info in your JWTs.
I am looking with Apache shrio framework. Looking at it authentication and authorization features can i build Identity server provider using shrio framework.
Is it possible to have features like,
Single Sign On
SAML support
Federation based on attributes
Do we need to write everything from scratch or shrio has some API's to handle such kind of features.
I read the documentation where they say about having SSO features based on Sharing of user session with multiple organizations . But i did not see any direct support API's to handle this.
To act as an IDP what shrio gives and what it does not support?
Please suggest.
Thanks,
Sohan
Shiro is a security layer that sits in front of your application. It is a security framework for a (SP) Service Provider that will issue an Authentication Request to your IdP (Identity Provider).
Open source IdP implementations that support SAML:
http://www.gluu.org/docs/
https://shibboleth.net/
This Stack Overflow question covers a way to use SAML to authenticate your user before they reach the application and provide the user's credentials as part of a http header.
Integrating Java Web App with SAML SSO
An alternative to installing and maintaining your own IdP.

The cost of developing, securing, and maintaining your own identity provider are likely much higher than paying a monthly fee.
I am researching on this topic last weeks and unfortunately I can't figure out. I understand the difference between authentication and authorization.
I will appreciate any guidance on the topic.
What I need as general is to implement single sign on for several web sites which are driven with apis which also should handle authentication. The users should be able to register/login with username/pass or respectively through any third party service like facebook, google+, twitter etc.
In the scenario above what is the better approach? Should I use only identity server, or only authorization server or both?
Thank you in advance.
Start with IdentityServer - this is your identity management system.
AuthorizationServer in addition is a full featured OAuth2 implementation that can use IdentityServer as a user store.
http://leastprivilege.com/2013/06/16/relationship-between-identityserver-and-authorizationserver/
Your scenario is more like Authentication which is confirming the identity of the user. On the other hand Authorization is if a person or if a role can execute some operation.
When Identity Server 3 was launched, it deprecated AS: The Future of AuthorizationServer, because all the AS features ase now included in IS.
We are working in an iOS application and we use back-end in azure. We have 2 types of login, one is Facebook login (using Fb as identity provider) and the other will be login directly to our system.
We decided to use ACS but we had a bunch of technical problems. My question is is it possible to create custom identity provider, which will be a service (for example WCF or WEB API) to generate a token that we pass the ACS to get the claim token. Does ACS support that kind of service interface? If so what what is the practice of generating tokens in our custom identity provider?
Thanks in advance,

ACS can support any identity provider that speaks a protocol it understands. Depending on the backend behind your identity provider, you can use something like ADFS or write your own identity provider using WIF. ACS doesn't support mixing and matching web-based identity providers with WCF-based ones, which means that you'll need to expose a website that ACS can redirect a browser to using the WS-Federation protocol. The only external contract you have is that ACS will redirect users to you and you need to log them in (what that means for your IdP is up to you) and issue a token back to ACS.
There are literally whole books on how to write your own STS using WIF, to get started there are a number of resources that can help, including the WIF SDK (which provides a template for the STS), this whitepaper (see the section "Using Windows Identity Foundation to Build a Security Token Service"), or this blog post.
