My Application in ASP.Net 4.0 Webform version. Application runs on SAAS based model. Deployed on Internet.
One of the client wants to use ADFS for SSO implementation.
When user logged in domain local intranet and try open Application deploy on Internet then he should be automatically logged into the application.
Process Flow will be
User Logged into Domain
Open Browser and try to open Internet application
Authenticate user with ADFS and Valid user then return the Claims
Any Blog or MSDN - how to configure ADFS (we did at our end but when user redirected to ADFS it again ask for Login from ADFS).
How to achieve this?
You are talking about IWA - refer this (page down).
Note this is browser functionality.

One of my customers wanted to implement SSO using ADFS. I was thinking to do a POC for the same using ADFS in Azure. But one requirement is only some users have ADFS login and other user needs to use custom authentication using the identity provider.
Is it possible to use custom and ADFS authentication in the same web application? Like presenting a page with sign-in using SSO or sign-in with credentials?
My client just shared the federatedmetadata.xml. (Do we need to give the full URL DNS name + metadata URL when you create the new project?).

If you're open to it, you could integrate your application with an identity provider, and that provider does this for you.
For example:
Your application integrates with CAS as the IDP, and CAS presents this screen to the end user for the authn attempt. User can choose either option, and then once completed, they will be redirected back to your application to continue, and your application interacts with CAS to validate the user account/session. CAS itself is connected to your own account store, and is also integrated with ADFS.
What do you mean by "ADFS in Azure". The only way to do this is to run ADFS as a VM in Azure. Otherwise, you would use Azure AD.
Yes, you can federate ADFS with other identity providers so they both are accessible from the same login screen.
What other identity providers are you looking at?
ADFS is not a project, it's a server add-on and it's all done via configuration on the Windows server.
In terms of importing metadata, see this.
We have a SharePoint 2016 farm with 8 servers. Also, the load balancer server is functioning to balance the request between the web-front-end server(s). The web application is configured to use the ADFS as an additional authentication provider while the default is "Windows Authentication NTLM" also using at the same time in the default zone. As the web application has two authentication providers - ADFS and Windows - every time the user has to select the authentication method. If "Windows auth" is selected the user will enter his or her internal Active Directory account manually to login into and if the user selects ADFS, request go to ADFS and redirecte to Azure login as the relying party and a claim is configured. The ADFS thing is ok for me as it is working as expected.
But I want to resolve the intranet users in intranet network itself (Pass-Through Authentication). As we know ADFS has the capability to authenticate intranet users in company networks by setting up the ADFS property by Set-AdfsProperties -IntranetUseLocalClaimsProvider $true to have all intranet users use AD and not be redirected to Azure AD but somehow it's not affecting anything. The cmd is runing successfully but not working.
Is there any additional configuration related to ADFS or SharePoint which needs to be done to archive pass-through authentication or autologin for intranet users who have logged into the machine using AD accounts?

We are having one web site which is developed in ASP.NET and VB code base and It has the normal forms authentication with username and password.
One of our client whats to setup the Single Sign On with our web site and they set up ADFS and gave us the Metadata xml file and We have created STS reference to that url and shared our website Metadata for them to add Relying party Trust.
when I access our website it redirecting to customer page and once they enter the login credentials and it's coming back with the Claims which is good.
Problem :
1).Now who ever access our website all user is automatically redirect to client ADFS login page which should not happen.Users should be Prompt with Our login page and it shouldn't automatically re-direct to client ADFS. If user Wants to use the SSO then it should be re-directed to client page ? How to handle that in programmatic ?
2).If one more client also wants to use the SSO with their IDp then how to configure more than one IDP for One web site?
Thanks.
WIF or OWIN?
WIF by default protects all pages.
You could un-protect your login page (location tag) and then if SSO redirect to a dummy protected page which will cause WIF to kick in.
Beware: for older apps. WIF and FBA in the same app. can cause problems.
The classic way to handle 2) is to federate the two ADFS. Then a user will see a Home Realm Discovery screen and get to chose which IDP.
We have an ASP.NET application using Forms authentication (ASP.NET Membership). Now we would want to make it to be claim-aware ASP.NET application in below scenario:
ADFS acts as an IP-STS for intranet (AD) users
If AD User is not mapped to ASP.NET Membership User or mapped ASP.NET Membership User does not have permission to access application --> Fallbacks to form authentication (an external IP-STS)
If end-user accesses the application from outside the domain, we don't want ADFS to prompt for Windows Credentials. We would like redirect end-user to out external IP-STS using form authentication.
Is this scenario achievable? Or is there any other possible solution? And how should I setup/configure my application?
Thanks
The classic solution to this problem is to have two ADFS with a split DNS.
Internal users redirect to an ADFS in the Intranet configured for WIA.
External users redirect to an ADFS in the DMZ configured for FBA.
For your second point, not clear if internal or external user.
If external (i.e. FBA) then you can modify the Forms login page, access AD yourself and redirect appropriately.
I am developing an ASP.NET Web application which should be accessible to the users who can access from both intranet and internet. Could you suggest the approach to implement this with ADFS 2.0.
The requirement is when users are logged in in the intranet the authentication to the app should be seamless without giving user id and password. Whereas for the same users if they are accessing out side intranet it should take email id and password as creditentials and authenticate.
You can put an ADFS proxy in front of ADFS for external users which by default uses Forms.
Internal users will get Windows Auth.
ADFS out-the-box only allows authentication with user name.
You would have to do some custom development - refer Adjusting the Home Realm Discovery page in ADFS to support Email Addresses.
