ADFS server 2016 supports openId connect. I have external organization that hosts ADFS server , I want my web application to get authenticated from External ADFS server using openIdConnect .
Question : As per Microsoft docs . If we want to consume external organization's ADFS we should host ADFS in our organization also. My application should trust ADFS hosted inside my organization ,instead of trusting external ADFS directly.
Here I want to know why we cannot directly trust External ADFS using opendiconnect ? It seems possible. what is reason of not trusting external ADFS directly?
Both models work. If your application plans to have users from multiple organizations, it is better to have your app trust an internal org ADFS which can then be federated to multiple of these organizations with simple configuration changes. This makes the application simpler where it is dealing with only one IDP. An additional advantage for having an internal ADFS is that any authentication policy changes can be managed fully at internal ADFS layer and not potentially requiring application changes.
However, if your application is only going to support one external organization, you can do this directly in the application. Both models work for this.
Hope that helps.

I have an SPA web app using openidconnect for authentication and authorization with local keycloak.
This app is now moving to an windows onprem infrastructure using AD, kerberos tickets and a central SSO.
users log in in their windows session, and then we shall be able to transparently login in our SPA web app. (ie with out entering credentials)
How can I convert kerberos ticket/authentication into Openidconnect world? Where is the magic?
Shall we add some kerberos in our app?
how can we retrieve our access token containing the user role?
thanks
Your SPA should continue to talk to Keycloak using OIDC, and no code in the SPA should need to change. Your APIs will also continue to receive the same access tokens.
You should only need to configure Keycloak to use AD for authentication as an LDAP data source. Here is an article on how to do that. It is an infrastructure job rather than just a coding one, so I would recommend collaboration with AD administrators on the environment setup.
AD is only one possible authentication method, and by doing things this way you keep your options open. You are likely to need to perform account linking, eg to identify users the same before and after the migration. There may be some data setup involved here, eg ensure AD has the same emails as the existing system.
Currently looking to federate servers that use AD. First thought was to use ADFS to manage service requests across domains and realms. That being said the application must have access to Kerberos tickets for a specific use case.
Does AD FS use Kerberos at any point or is it it's own totally redesigned ticketing system? If so can you create a hybrid application that can authenticate using ADFS and request tickets using Kerberos?
ADFS simply provides a federation service on top of AD i.e. support for protocols like WS-Fed and SAML.
The Kerberos protocol remains part of AD.
Once authenticated ADFS provides either a SAML 1.1 or 2.0 token that contains the claims.
We are trying to federate our application, so that our customers can gain access to our application using their respective corporate identities.
Well, I understand the mechanism of federation process, I’ve been able to setting up ADFS and I’ve modified the code of our application for accepting claims into my lab environment and all work fine.
In the next weeks I’m going to build a federation trust between ADFS and our customer’s product (Ping Identity) and I need your help to understand what kind of information I’ll have to exchange with customer’s IT department to complete that step.
I’ve never been experience with Ping Identity products.
Appreciate any help.
Many Thanks
I am going to make a couple of assumptions about your application, mainly that it is .NET application hosted on IIS. This type of application integrates Windows Identity Foundation (WIF) using tags in the web.config and then reads the authenticated users identity information via the Claims Identity object passed to your application. In this case your application is referred to as the Service Provider (SP).
If your customer is using PingFederate, the integration is straightforward in that a WS-Federation SP Connection would be configured on their server referred to as the Identity Provider (IdP). If your customer is using PingOne, then the integration will be tricky.
The information to exchange for PingFederate is driven by the configuration in the configuration in web.config. You need to configure the thumbprint which is based on the digital signing certificate of the WS-Federation response containing the SAMLv1.1 token. Your customer will be able to provide the thumbprint value. You will also need to configure the federated authentication URL, issuer, and realm, which is the information about PingFederate IdP server. The issuer is the URL for your SP application to redirect to the PingFederate IdP server, along with the realm which equates to the PingFederate SP Connection. Be sure that you configure the audienceUris to be the same value as the realm. The PingFederate administrator will need to know your Service URL endpoint which is your SP application endpoint to receive the WS-Federation response with the SAMLv1.1 token.
I installed PingFederate on an AWS EC2 running Windows_Server-2008-R2_SP1-English-64Bit-Base-2014.04.09. I have a Java application that is using Spring Security for authentication.
I have read about how with PingFederate, I can set up an Identity Provider(IdP) and a Service Provider(SP). I have gathered that the IdP would be the Application User providing login credentials(the Identity) and passing this to the SP which has the Target Application apart of the SP in this diagram on this page here:
http://documentation.pingidentity.com/display/PF66/Service+Providers+and+Identity+Providers
This image also shows the Federated Identity Software on both sides of the IdP and the SP.
I have created an IdP and SP with my local PingFederate server just to see what the configuration options are and I am confused on which parts of this I actually need to be able to have a SSO for my Spring Security application.
My questions are:
Do I need an IdP and SP to implement that I am trying to do.
Right now our usernames and passwords are stored in a SQL Server, would I leverage this for PingFederate to use to authenticate the users?
Should I even be using Spring Security SAML for this or would another route be more appropriate?
Thanks for any help, I have reached out to PingFederate but my Regional Solutions Architect happens to be out until Friday.
I also apologize if I am completely off in my thinking, I am trying to wrap my mind around what is needed.
Presuming your goal is to establish federation between Ping and your application (in order to e.g. externalize authentication or enable single sign-on), your thinking is correct.
The Ping Federate serves as an Identity Provider (IDP) and you can configure it to connect to your SQL server, so that it can authenticate your existing users from there. IDP communicates with other applications which are called Service Providers (SP).
In order to connect to Ping your application therefore needs to be able to act as a SAML 2.0 Service Provider and using Spring SAML is a very good way to enable it to do so.
The typical flow of data between SP and IDP for single sign-on is similar to:
User accesses SP application which requires authentication
SP creates an AuthenticationRequest and sends it to IDP (using redirect in user's browser)
IDP processes the request and authenticates the user
IDP responds back to SP with an AuthenticationResponse message
SP processes the response and creates a session for the user based on the included data
There is an assumption being made that you need SAML between your Spring app and PingFederate. That is not true depending on how it is deployed and if you (see Andy K follow-up questions). You should check out the OpenToken Integration Kit for Java or perhaps the ReferenceID Int Kit from Ping as a possible solution. Much simpler to integrate than trying to hack together another SAML solution that may not be needed. However, I would recommend talking to your RSA who can give you the best approach for your scenario.
We are doing a Cloud POC, we will have applications hosted in the cloud that can only talk LDAP. Is there any system/appliance/virtual directory in the cloud that can appear to be an LDAP server from the application side, and on the output side talk SAML/REST based over the Internet to talk to our SSO product that can authenticate users against our corporate LDAP, which is tucked inside our internal firewall?
You need to deploy an Identity provider connected to the ldap. You can adopt CAS or SAML technology.
In that wikipedia entry you can check the differents products (commercial and free software):
http://en.wikipedia.org/wiki/SAML-based_products_and_services
Most of them support Ldap as the authentication source backend.
Also Take a look on this thread:

The emerging SCIM (System for Cross-domain Identity Management) protocol might make more sense for the use case you're illustrating. It's intended to provide a simple REST API around an identity store so you can perform Create/Read/Update/Delete operatons. What will be available could theoritically be controlled via some policy within a SCIM server to alloy your clients to essentially interact with the backend LDAP directory.
Many products are adopting the SCIM standard now, such as ones from Ping Identity, Salesforce and UnboundID.
