Can anyone tell me how can we use SSO/ADFS authentication in dot net app.
You add the WS-Fed OpenID NuGet package.
Ideally, you would use OpenID Connect but you need ADFS on Server 2016 for that.
Refer: Use the OWIN Security Components in ASP.NET to Implement Web Sign On with ADFS.

I am trying to create a login mvc application in .NET through which any identity provider that supports OpenIdConnect for authentication and Oauth2.0 for authorization should be able to communicate. The objective is all my microservices will then call the login service ( which will act as a proxy) to perform single login and single logout and authorization via different identity providers such as Ping Identity or Okta or perhaps Azure AD. I am using the package Microsoft.AspNetCore.Authentication.OpenIdConnect to achieve this.
I don't have much experience setting up ADFS authentication in the .NET stack so forgive my ignorance if I am missing the obvious. But if some one can point me in the direction on how to configure ADFS and write a .NET Core application to request Oauth2.0 supported tokens from it, would help a lot. Please know that I am trying to connect with ADFS 2012 R2 , which supports Oauth2.0 Authorization code flow.
ADFS 2012 R2 does not support OpenID Connect and has no concept of an ID token.
You need to use ADFS 2016 or above.
What I know about IdentityServer and OpenID connect is:
The IdentityServer is a free, open source OpenID Connect and OAuth 2.0 framework for ASP.NET Core. That incorporates all the protocol implementations and extensibility points needed to integrate token-based authentication, single-sign-on and API access control in your applications.
Further more OpenID Connect is a simple identity layer built on top of the OAuth 2.0 protocol. OAuth 2.0 defines mechanisms to obtain and use access tokens to access protected resources, but they do not define standard methods to provide identity information. OpenID Connect implements authentication as an extension to the OAuth 2.0 authorization process. It provides information about the end user in the form of an id_token that verifies the identity of the user and provides basic profile information about the user.
What I want to know is what is Azure Active Directory and How it is works? Did we use Azure AD with openid connect? or it is optional with openid connect? and If I've an webapi which is based on ASP.Net core 2.0 with identityserver 4. Did we deploy on azure without implement Azure AD? I m confused because I've an webapi project and a client project based on angular. when I deploy my client project as a new web app on azure its running fine. But when I deploy my web api on azure its not working. Means after deploying my web api when I do post request to get a token or when I want to register a user through my azure web api link it shows me 500 error in postman.
After facing this problem I post it on Here Stackoverflow but didn't find any helpful answers. So I again start searching and found that if we want to use openid connect with azure we must implement Azure AD. Here is the Reference. So in this question I want to know the difference between openid connect and Azure AD? and second question is. Is this possible to use openid connect without using Azure AD? Please explain your answer briefly. Thanks
I've been trying to implement the SP initiated SSO with ADFS 2.0 configuration. But I could not find any solution to do that.
Not sure if the ADFS 2.0 supports the SP initiated SSO. I can see there are some third party libraries to do that but I don't want to use any third party libraries. I just need information on posting SAML request to identity provider and getting the SAML assertion back to the survive provider.
Here Service Provider is my application(asp.net) is and ADFS 2.0 is the Identity Provider.
Any idea how I can achieve this.
Thanks.
Your problem isn't ADFS - it's ASP.NET.
.NET has no SAML support. You need a third-party stack.
Refer: SAML : SAML connectivity / toolkit.
ADFS definitely supports the SP initiated SSO flow.
We are using symfony2 as our framework to built the application which has different firewalls like admin, client and customer.
Now I want to built SSO using SAML(CAS) or OPENID in symfony2. Which will communicate with my application and provide the authentication and with other applications also through web service.
Please suggest some bundles which are already built for SSO and which is better SAML or OPENID.
Thank you in Advance.

I'm not sure if you want to use CAS, SAML or OpenID protocols, but here is an example of a CAS client for Symfony: https://wiki.jasig.org/display/CASC/Symfony+CAS+Client. It might help.
I will soon need to add SSO to an ASP.NET app using SAML. The client will not provide access to their Shibboleth identity provider for testing, so I'll need to verify that SSO works myself.
What would be the easiest method to use/setup a SAML identity provider for testing? I'm not keen on having to setup an infrastructure myself if I don't have to.
I'm planning on using a SAML component from http://www.componentspace.com/
If you are a SaaS Provider - Check out "Getting Ping Certified"

All your suggestions look quite helpful.
For others who may find this page, the ComponentSpace SAML 2.0 component comes with an Identity Provider that appears to mimic Shibboleth. This appears to be the easiest way to test adding SSO to your own application.
