We have a ADFS server farm running version 3.0. Right now, we have it enabled to authenticate 3rd party vendor applications. We are planning to leverage this existing server farm to generate a JWT token for it to be consumed by our in-house custom applications. Does anyone know the steps to be followed for generating a JWT token which returns all the AD groups associated with the user?
Configuration - Windows Server 2012 R2, ADFS 3.0.
Can use either OAuth or SAML.
Please help.
This link should help.
Note that you should really use OpenID Connect for authentication but that's not available on ADFS 3.0. Also the user case for ADFS 3.0 OAuth is web API not application.

I have created a Web API using .net core 5. I have secured the app using the Microsoft Identity platform. Clients app are able to get to the resource based on their scope/role. So I know that my api is secure.
Now, I need to add the API to Azure API Management tool.
So my question is should I enable OAuth from the Azure API Management to secure my web api even though my app is already secured?. What would be the reason that I enable OAuth from API management?
APIM is a proxy to the backend APIs and implementing security mechanisms to give an extra layer of security to prevent unauthorized access to APIs is a recommended practice.
Configuring OAuth 2.0 Server in APIM merely enables the Developer Portal’s test console as APIM’s client to acquire a token from Azure Active Directory. In the real world, customer will have a different client app that will need to be configured in AAD to get a valid OAuth token that APIM can validate.
OAuth is an authorization framework which allows a recognized client to acquire an access token from an authorization server.
As given in this Microsoft Doc, the Microsoft Identity Platform uses the OAuth 2.0 protocol for handling authorization.
Please find below references makes you how OAuth secures the Web APIs/Services:

We have an existing MVC angular application enabled with ADFS WS-Fed authentication. The application has many API's hosted as a part of the solution which is internally accessed by views. Now, We have a requirement for the API to be published to other developers.
I am thinking of enabling OAuth/OpenId for the endpoints and enable other developers to access. I need your inputs regarding my approach.
There is no support in ADFS 2.0 for OpenID Connect and OAuth.
The only API option you have is via WCF.
Configuration: We are using Identity Server 3 with a Web API 2 application, a mobile phone application and an upstream identity server.
Problem: The upstream identity server supports OAuth2 but not OIDC.
Question 1: Does Identity Server 3 support OAuth2 without OIDC to the upstream identity server?
Question 2: Do I need additional configuration to make OAuth2 work without OIDC?
Just to give a bit of understanding about OAuth2 and OIDC:
OIDC is extension of OAuth2. OAuth 2 isn’t about authentication. It’s all about authorization. https://www.rfc-editor.org/rfc/rfc6749 OIDC is a simple layer on top of the OAuth 2 protocol that deals with the end user. http://openid.net/specs/openid-connect-core-1_0.html
I’m not exactly sure about your implementation detail but Identity Server 3 supports OAuth2 as well as OIDC and it all depends how the client is setup (flow) and what the client asks in terms of a “ResponseType” as part of a token request to Identity Server 3.
I know this may not be an answer to your 2 questions but I think you need to think of the interaction between the Client (mobile phone application), Identity Server 3, and the Upstream Identity Server. If the Upstream Identity Server does not support OIDC then it does not care about authentication of the end user and therefore I would think that it only requires some sort of clientId/clientsecret that could be passed as part of the request to get a token? Machine to machine (Client Credential Flow). So maybe your mobile phone application calls the Upstream Identity Server in a different fashion then it does Identity Server 3? Hope this helped a bit. Cheers
I have generated a Client ID and Client Secret for my application using the Google API Console for my Java web application.
I want to generate an access token to be used in my application to authenticate a mailbox and read mails from there with the help of JavaMail API.
This link has some theoretical information but I could not understand how the tokens can be obtained.
Answer will depend upon where is application running as it determines how access token can be received:
Using OAuth 2.0 for Web Server Applications
OAuth 2.0 for Client-side
Web Applications OAuth 2.0 for Mobile & Desktop Apps
OAuth 2.0 for TV and Limited-Input Device Applications
There are different alternatives or libraries available to get access token depending upon the type of application and different specific mechanisms are defined around it.
So it will be then much easier to dive-in into the specific options available.
In simple My only requirements are to implement SSO in my application:
Use ADFS 2012 R2 for SSO (OAuth2 protocol).
User will get token using oAUth 2.0 VIA ADFS Server using login prompt for credential or what ever authentication scheme is configured on ADFS form based or windows based.
If same user that is authenticated using oAuth for one application if second application want to use the same user then the login box that ADFS presented using oAUth2.0 should not appear.
Now, please help me how OWIN.SECURITY.OAuth or any other oAuth will help me and what is the best way to implement in MVC web application. Please provide sample applicaiton.
ADFS 2012 R2 only supports public clients. Web sites are confidential clients, hence you cannot perform an OAuth2 authorization grant with ADFS 2012 R2. But you should not be too bummed, given that an OAuth2 authorization grant would not give you SSO anyway - OAuth2 is not a sign on protocol.
If you want to perform web sign on using OAuth-like technology, I recommend you consider OpenID Connect and the ADFS version that comes with Windows Server 2016 (currently in technical preview 4).
