I am developing a website that should authenticate users using ADFS.
Basically, we have a CRM Dynamics deployed on a server, and the CRM Dynamics is having ADFS authentication.
Now, I am writing a .NET website that will target the CRM Dynamics and that .NET website will be available to public.
In order to implement authentication using ADFS, I read about this blog, but most of the information are unclear.
Anyone having an experience implementing ADFS authentication in ASP.NET site?
Any help on this much appreciated.
thanks
This is standard workflow for a claims-enabled ASP.NET application.
e.g. Building a test claims-aware ASP.NET application and integrating it with ADFS 2.0 Security Token Service (STS).
This uses VS 2010. In VS 2012, the same utility is called "Identity and Access Tool". In VS 2013, it's part of the project creation.
Basically:
Create your application
Add WIF as reference in .NET 3.5
Update web.config using above utility
Add your application as a Relying Party in ADFS
It is possible but it may effect some security issues..
This is the way you can do..
Host your application in Static ip
Create users in your AD who and all are need to access the application from outside
Try to access from public
Ask the credential first time.
Dis adv: Security issues

I have a traditional ASP.NET 3.5 Web Forms application. As of now it is using On-Premise ADFS which is working fine. Now we have a requirement to change on-premise ADFS to Azure ADFS.
In the web.config, I have changed the required URL to point to Azure ADFS but it is not working. I checked Stackoverflow and Googled around but I found examples related to ASP.NET MVC and ASP.NET Core where changes are required in Startup.cs file.
I want to know what all changes are required in my traditional Web Forms application. Any example link would help.
You should be able to get it working by using the Azure AD parameters rather than the ADFS ones e.g. metadata. What protocol are you using?
There are some ADFS samples. Look at the LHS under ADAL and MSAL. These generally start with an Azure AD sample and show how to convert to ADFS. So you can then work "backwards".
Update
I had a look at that code. It looks like OIDC? "Redirect_Uri" is not a WS-Fed parameter.
There is a WS-Fed sample here.
I already have more than 10 applications developed using ASP.NET. There are different versions for frameworks 2.0, 3.5 and 4. Currently I need to apply single sign on on all of my applications using Windows Azure Active Directory SSO. But I do not know what the code or library should be added to my application to be configured with the Azure SSO. Do I need to re-develop my application or recreate it with different versions? Does anyone know what I should do?
Different .NET frameworks should not be a problem. You should be able to implement SSO for all of these applications, but you will need to add it individually to each one. You will need to add it in the code of the application itself and then register each application to your tenant.
Here is a very good tutorial that shows you step by step how to add SSO to a published web application in Azure using OpenID Connect. You can follow the steps exactly and build their demo version to test it out, or follow their steps at the bottom that show how to implement SSO in your own application.
https://github.com/Azure-Samples/active-directory-dotnet-webapp-openidconnect
Here is the official Microsoft documentation, which also describes how to implement SSO: https://learn.microsoft.com/en-us/azure/active-directory/active-directory-saas-custom-apps
Alternatively, if you want to use a library that is already integrated with Visual Studio, you can go to Project > Add Connected Service > Authentication with Azure Active Directory.
The "SSO" in this case refers to SAML. To do SAML in C#, look into Windows Identity Foundation (WIF), which includes some SAML support.
Note that doing SAML SSO involves more than just dropping in the right kind of username/password field. You need to have additional special pages to handle certain redirects, and have a way to store exchange saml metadata with your Azure AD identity provider. It can be painful.
I have been tasked to set up Single Signon for asp.net application (SAAS) using IIS server with a client who has ADFS3.0 for providing identity credentials. the users authenticated will be allowed to log in to the web application but i have been going through a lot of information as how to set up service provider files as the application is already running.
what settings and where do i need to configure them. any help will be greatly appreciated.
The "modern" way to do this is by using OWIN.
You will have to change your application as per Use the OWIN Security Components in ASP.NET to Implement Web Sign On with ADFS.
Then add your RP to ADFS and you are good to go.
For completeness. the "old" way to do this is to use WIF as in How To: Build Claims-Aware ASP.NET MVC Web Application Using WIF.
I have created an ASP.Net web app and hosted it on MS Azure where users sign in and are able to log into the system. I am not using Azure AD or on-premise AD but using Azure SQL database. Users are registering on the web app as normal users. I would like to know if there is a way to integrate Azure Multi Factor Authentication with my custom written app.
Any clarifications required, please ask.
From your question it sounds like you're using some kind of ASP.NET identity feature which uses a SQL database as the backend. If so, then you might want to take a look at this article:
http://www.hanselman.com/blog/AddingTwoFactorAuthenticationToAnASPNETApplication.aspx
It shows in detail how to configure multi-factor authentication for an ASP.NET application using ASP.NET Identity 2.0. It should work regardless of whether you're hosting on premise or in Azure.
If you're asking how to integrate Azure AD Multi-Factor Authentication into your existing ASP.NET identity subsystem, then I fear that may not be possible unless you take a dependency on Azure AD as your identity subsystem.
Need to develop a Web application that will be used to authenticate and authorize internal and external users to log and then re-route to web applications for the organization. The login application should be able to provider smooth integration with any future applications that needs a secured authentication.
Should I be using WIF - Claims based Identity/ADFS or asp.net Role membership provider to develop this app.? Or is there any other approach which will help achieve this?
I've been working on an asp.net site with WIF for several months now. I like that WIF is very flexible, but the documentation is poor. Check out the discussions on SO about WIF.
