I'm trying to federate on premise ADFS 3.0 instance with Azure Active Direcotry instance. The idea is to allow AAD (azure) users to authenticate to an application which trusts the ADFS instance.
I added azure AD to claims provider trusts in ADFS (using it's federation metadata document path)
then I create an application in AAD which has identifier of the ADFS (e.g. https://fs.somedomain.com/adfs/services/trust
ADFS instance then correctly displays AZURE as special realm.
The only thing I can't figure out is what should be the reply url in azure application settings, so the ADFS instance redirects authenticated request to correct application.
It's the normal adfs/ls.
You just need to configure the URL and URI.
Refer: Azure AD as IdP with AD FS as RP.

Newbie to Microsoft SSO Authentication.
Have metadata, pubic cert and login url and Azure AD identifier and entityid.
When I was going through this SAML2.0 i see diff types of auth strategies like Federation Services, ADFS, Active Directory, Azure Directory... Getting confused and trying to visualize the type of authentication these details support.
https://learn.microsoft.com/en-us/azure/active-directory/develop/tutorial-v2-nodejs-webapp-msal
Can somebody point me what type of authentication that we can provide with below details ?
metadata, pubic cert and login url and Azure AD identifier and entityid.

We install adfs on Windows Server operating systems. It extends on-prem identities managed within AD to cloud applications through both SAML and OAuth. AD FS is meant for on-prem environments and does not authenticate through Azure infrastructure; it only authenticates against Active Directory.
AAD mainly serves as a cloud-based user management, as well as offers SSO capabilities for web applications. In fact, it authenticates users to their applications in much the same way as AD FS. The difference is that AAD authenticates via the cloud and AD FS authenticates on-prem.
Federation - When you set up SSO to work between multiple identity providers, it's called federation. An SSO implementation based on federation protocols improves security, reliability, end-user experiences, and implementation.
With federated single sign-on, Azure AD authenticates the user to the application by using their Azure AD account. This method is supported for SAML 2.0, WS-Federation, or OpenID Connect applications. Federated SSO is the richest mode of SSO. Use federated SSO with Azure AD when an application supports it, instead of password-based SSO and Active Directory Federation Services (AD FS).
So, if you want authenticate with cloud users you can go with azure ad or else if you want to use your on-premise user identities authenticate users for the application you can go with ADFS.
You can find more information here What is single sign-on? - Azure AD | Microsoft Docs
Differences between ADFS and Azure AD
I understand that ADFS is a STS (Secure Token Service) in the sense that it issues tokens to applications that helps applications establish user identity. At an organization level, our org uses ADFS with WS-Federation protocol to authenticate users across all internal application of organization and also implement SSO.
Also in our organization we have Azure AD account, and I have used Azure AD to register our custom apps, and whenever an unauthenticated user enters our app, the person will redirected to azure ad login page and will have to authenticate himself. After successful authentication Azure AD also issues token(ID Token, access token, Refresh Token)
My question is that can I consider Azure AD also a type of STS (Secure Token Service) just like ADFS because it issues tokens to establish client identity?
ADFS only handles authentication and authorisation. It does not handle user provisioning.
In that sense ADFS is not an Identity provider, It's just a STS.
You need separate instances of ADFS (auth.) and AD (user). AAD combines both.
As its name implies ADFS is a federation layer that sits on top of AD.
Also, ADFS is an R-STS in that it can be in the middle of a federation chain. It can handle upstream and downstream requests . AAD can't - it is always the endpoint.
ADFS has the power of claims rules, AAD has no such concept.
Both work as a secure token service.
These are two different services of course, and usually you are responsible for the ADFS infrastructure, while you are not responsible for AAD infrastructure.
Azure AD can also federate authentication to ADFS if you have user sync enabled with Azure AD Connect.
In that scenario Azure AD redirects the user to ADFS to authenticate, and trusts the answer ADFS provides.
From the point of view of apps it makes no difference how a user authenticates against AAD.
We have the following scenario:
an Angular app accessing a Web Api backend
our own user database
We are planning to use a third-party identity solution such as Azure AD B2C, AWS IAM or Auth0. To my surprise, I found that Auth0 has an integration with on-premise Active Directory, but Azure AD B2C seems not to support this (at least not that I could find out)
We want to get to the following scenario:
an Angular app accessing a Web Api backend
third-party identity solution that manages the users of the angular app (preferably Azure AD B2C)
users need to authenticate via the identity solution (e.g. using a social account)
some users are in an existing on-premise AD and also need to be able to access the angular app
So my problem basically is : if we would use Azure AD B2C, how can we let users that are defined in an on-premise AD, authenticate in our Angular app? Or with other words: can an on-premise AD be an identity provider for Azure B2C?
This scenario can be solved with AD B2C custom policies.
I found that Auth0 has an integration with on-premise Active
Directory, but Azure AD B2C seems not to support this (at least not
that I could find out)
One way I know to make this work through ADFS. Where you can Integrate ADFS in B2C. I will update this answer if I know any other way of doing this.
Update Start
You can use Shibboleth and Okta servers apart ADFS server.
Update End
users need to authenticate via the identity solution (e.g. using a
social account) some users are in an existing on-premise AD and also
need to be able to access the angular app
If you use custom policies, you can achieve all of these scenarios. You can integrate both social accounts and AD via ADFS (On Premise ADFS server which give access to On Premise AD users)
if we would use Azure AD B2C, how can we let users that are defined in
an on-premise AD, authenticate in our Angular app? Or with other
words: can an on-premise AD be an identity provider for Azure B2C?
As I said this is possible through ADFS server. All you need to do is enable ADFS service on your server and add Relying Parties and make B2C consume and allow your AD users to login with B2C.
Warning: If at all your server not have ADFS enabled first try it on other test server.
ADFS in custom policies can found at: https://learn.microsoft.com/en-us/azure/active-directory-b2c/active-directory-b2c-custom-setup-adfs2016-idp
"I have an application where I have users authenticated with multiple directories all federated using a ADFS. There is a central ADFS that does the federated and routing to the correct IDP. Most IDP are ADFS that add claims to the SAML token by using the normal ADFS rules. We now have some customers that want to use Azure AD as IDP, but this seems not to allow to add claims like ADFS.
What would be the way to add custom claims to a saml token using Azure AD?"
You can do this by adding your application in Azure AD Directory Portal via the Application Gallery. This gives you the opportunity to add claims to the outgoing SAML Token.
If you have Azure AD Premium you can add your own application (that accept SAML 2.0) and configure the extra claims via the "Attributes tab"
If you or your customers do not have Azure AD Premium you will have to have you app added to the Azure AD Application Gallery. The process for this is described in https://azure.microsoft.com/en-us/documentation/articles/active-directory-app-gallery-listing/
We are developing a multi-tenant application and would like to be listed on Azure and support Azure AD as an IdP for our customers. However, a few customers that already have ADFS 2.0 setup didn't like the idea of sync'ing all accounts and passwords to Azure AD. So, is there anyway that when Azure AD receives a login request, somehow, have it redirect to ADFS and let ADFS do all the magic and return a token back to Azure AD which then returns JWT (using OpenID Connect) to our application?
I know that ACS supports such scenario but we are worried that Microsoft would soon drop support for it.
Thanks!
