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.

So we are using IdentityServer4 for our web applications, all is good.
We have a new requirement from a client to allow them to perform SSO via their ADFS system using WsFederations, we already provide this for another one of our older web applications that is not tied into IdentityServer4 yet.
Ideally we would like to tie WsFedereration into IdentityServer4 so it is in one place.
Does anyone know if it possible to use IdentityServer4, so we redirect to IdentityServer4, identity that this particular client (possibly via an alternative URL), then IdentityServer4 authenticates against ADFS, collects the claims (probably basic, e.g. email/username/etc) , and we then supplement them with additional claims for access, and pass back to the web application.
What I'm trying to achieve ideally is to not change the existing Web Application, and to sort the plumbing at IdentityServer4, and the Web Application wouldn't know or care if this user was IdentityServer4 only or
IdentityServer4 + WsFederation. This would be useful for other clients across our applications to easily integrate in the future.
Alternatively I could deploy another version of the Web Application that authenticates directly with my clients ADFS system. However this seems a waste of server resources/maintenance for just one small client.
I had a look at the external options (where you click google on or near the IdentityServer4 Login Screen), is there a way to automatically redirect to the ADFS without event seeing the IdentityServer4 implemented Login screen.
Is this possible?
Thanks,
Jon
This was released 2017, see the example at

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've been scratching my head over this issue for over a week. We have a web app that we would like to implement SSO for. SSO with windows active directories of our clients (i.e. we essentially need to authenticate against our clients' active directories without much trouble)
The only thing I am 100% sure about is that I will needed a security token service that will have to communicate with an Identity Provider. My question:
Which service is most suitable for the above scenario (AD FS? OpenID & OAuth 2.0? SAML 2.0 and shibboleth?)
How will I connect to the active directories of the clients? Maybe I'm not understanding how the STS is to be used, could anyone clarify? I'm working with an Azure Web App
Will there have to be a different IdP for each client? Will the client have to do more than just give us standard information? What would this info be?
...should I be using Windows Identity Foundation?
HELP :( ... this is an SOS
If anyone could clarify at all, I will forever be grateful. I normally upvote anything I find helpful and accept whichever answer is the best so feel free to answer with what you think might be useful in helping me understand how I can achieve what I am after.
These are the three options I know:
As you mention one option is ADFS this solution means that your customers should install and expose Adfs. ADFS means Active directory-Federation Services, so in this case your application needs to speak WS-Fed (not oauth). Typically if the user is inside the LAN adfs uses integrated auth, if not it will prompt credentials.
WAAD is a new service from Azure, it allows companies to expose their directories to use in cloud applications. With this approach your customers need an account in Azure, create a directory and use the dir sync agent. Your application will talk SAMLP with WAAD.
Auth0 is an authentication broker that allows developers to use social but also enterprise identity providers like AD but also google apps, waad, adfs, salesforce, etc. if your customer only has AD you will provide him an msi for a windows service, that will bridge the company AD with your auth0 account, you can have as many AD as you want. Your application speak oauth with Auth0. This agent supports kerberos authentication as well. The following graph explains this solution:
Disclaimer: I work for Auth0.
WIF doesn't support SAML or OAuth.
Your application is in Azure.
Suggest add WIF to the application and then "bind" to Azure Active Directory. In VS 2013, use the "Change Authentication" feature for this.
Make the application multi-tenanted.
Each customer has their own tenant. User DirSync to sync. each customer AD with their AAD tenant. (That gives same sign-on). Adding ADFS to each customer gives single sign-on.
However, the customers will probably push back on this because of perceptions around security.
I'm trying to investigate possibility of using claims aware security in the system I'm developing. The more I read about all this stuff the more confused i get.
So i decided to describe what I know already and I would ask that You correct my statements. I got lost with all those protocols and technologies used.
Below is a simple diagram of my system. There are two services - a REST service implemented using WCF and an ASP MVC web application.
I know I need to get an STS which will be a trusted identity issuer for both of my services. I'll be using roles to differentiate certain levels of access.
The STS functionality might be accomplished by using ADFS (or is there anything more needed in addition to it) or WSO2 Identity Server.
By saying STS I mean a service which will get credentials from a client wanting to authenticate and will return a set of claims (which will beside other information contain the role assigned to the user). This set of claims will be in the form of a token.
On the diagram I marked different client types with different colors. No I'll try to describe what protocols/formats i think will be used. I am pretty confused on what is a format and what is a protocol. But let me try:
Red scenario: rich WCF client authenticates agains REST service
Request to STS will be sent using WS-trust (is there any other possibility in ADFS or WSO2?). The credentials might be in one of several forms such as X.509 certificate, password digest, kerberos, windows authentication, SAML token (this is used in federation scenarios, right?), and few other.
The answer to the client will be in a form of SWT token sent over OAuth protocol since this is the way we do it when trying to authenticate against REST services.
Does ADFS support SWT and OAuth? I couldn't find the information.
The client then send the token received from STS to the REST service. Once again this is SWT token on OAuth.
I guess as for the client code all can be easily implemented using Windows Identity Framework.
Green scenario: rich android client authenticates against REST service
All protocols/formats are the same as in previous scenario. Is there any framework which can let me easily implement this?
Blue scenario: user of web browser authenticates against ASP MVC web application
User goes to the web app's main page. The webapp detects that he isn't authenticated yet so redirects him to the sign on page on STS (the sign on page is on STS, right?).
and 3. STS authenticates the user and sends HTTP response containing SAML token and redirection to webapp. So here is HTTP used, not WS-Trusts.
Another question. In this web browser scenario there will be a cookie written on a client's machine. So whenever client will try to authenticate once again, he'll just send the cookie to sts to obtain the token. There will be no need to send the credentials. STS will issue a token basing on the cookie without any real authentication logic involved. Is that statement correct?
ADFS / WIF out the box only supports SAML tokens - no OAuth support.
ADFS / WCF uses WS-Trust.
The sign-on page is part of ADFS.
The answer is "Yes" to your last question but (at some point) it will expire and the user will have to authenticate again.
Update:
Have a look at Claims Based Identity & Access Control Guide
We have an Internet facing Web Application running, and recently our company made some agreements with a 3rd-party company which owns another web site. The idea is to provide access to this external web site to our current customers. Our users will click on an internal link in our solution which will open a new browser window with the third party site. User will not need to authenticate again in the 3rd party company site.
We have agreed to issue SAML2 tokens for our users, with a set of claims used by the 3rd-party site to query an present a personalized view to our users
Something important in our scenario is that users are already authenticated in our web site when they decide to access the 3rd-part web site.
What is the best way to implement all this?
I am thinking on implementing a custom-STS using the WIF SDK to generated those SAML2 tokens and pass then using HTTP POST (cookie) to the 3rd party site. If this is the right approach, then any pointers, tips?
Will ADFS make any difference?
Thanks for any help
Sounds like you'll be playing the role of Identity Provider - responsible for handling the "manual" authentication of the user and generating SAML responses to give the user SSO to the 3rd party website.
Implementing your own IdP is not trivial (there are a handful of specifications to understand), so unless you have your heart set on this as a development project, you may want to consider a COTS like Microsoft ADFS, PortalGuard (for whom I work) or Ping Identity.
Since you asked about ADFS specifically, it has native support for Active Directory as the user repository and has some interesting features with its claims transformation engine (if you get into a complex SP-IdP chaining scenario). Besides SAML it also supports WS-Federation which is important for integration with the other offerings in the Microsoft stack.
If your application is ASP.NET, then connect your application to ADFS.
So to get to your application, the user has to log in.
Then for the link to the 3rd party application use the IDP Initiated scenario (IdpInitiatedSignOnPage Class Overview). This sends a SAML2 token to the 3rd party application. ADFS will handle SSO for you.
To do this, you will have to configure the 3rd party application as a SAML one rather than a WS-Fed one.
