In ADFS on Windows Server 2019,
We plan to set the developed authentication provider as the only authentication method.
However, if I set a custom authentication provider as the only authentication method,
There was a problem that the content customized in Onload.js had not reflected.
We have confirmed that it has been reflected in the case of default Form Authentication.
What was customized in Onload.js is that you do not need to enter the domain name when entering the user ID.
If this became ineffective, it is quite inconvenient because the input increases.
Could you give me any advice?
Best regards,

I have configured thinktexture identity server which is connected with my database for authentication and returning the claims in response.
Now I am able to use STS in my website. Behavious of STS is, user is getting redirect to STS website login page for authentication and response is getting retun to my website after successfull login.
I want to implement a little bit different. I want to use Login page from my website itself instead of using this from STS so that stsyle and theming can be displayed as per my website.
Also want to implement many other password control features ie Password expiry warning, force change password etc can be implemented within the website.Please suggest the approach
Look into the WS-Trust endpoints that IdentityServer supports.
After a lot RnD, we finally reach at conclusion that it cannot be achieved.
It will always redirect to identity server URL for authentication.
I have a requirement to integrate an ASP.NET web application with active directory - basically they want to be able authenticate and authorize with AD.
I realise this is relatively simple, but what I want to know is how I can simulate the AD for developing and testing against. I don't have AD available to me (right now) and don't cherish the thought of setting it up even if I had hardware available to run it on.
What other options are available to me? I've seen ADAM mentioned in a couple of places but this doesn't seem to provide the federation services I need (and seems a little out dated). Would it be possible to use Azure for this? I want to keep costs (time-wise as well as money) to a minimum.
I have managed to set up an active directory environment suitable for development using a Microsoft Azure VM.
A brief summary of the steps I went through to get this working are below. Although it sounds scary setting up AD and ADFS, the windows server 2012 interface makes it incredibly easier, barring a few gotcha's I mention below - it takes a while for them to install as well.
Create a new azure windows server 2012 VM and add endpoints for http and https.
Install the AD role on the VM
Install the ADFS role on the VM
Create an ASP.NET MVC 4 app (on your dev machine) and verify it is working correctly.
Run the app through IIS (not IIS express - this just makes SSL etc easier).
Ensure the site has a https binding set up
Install the Identity and Access tool for VS2012
Right click your project to select the identity and access tool.
The path to the STS meta document will be https://<your VM url>/FederationMetadata/2007-06/FederationMetadata.xml (you may need to download this file manually if your certificates are self signed).
Back on your VM, in ADFS create a relying party trust for your application.
Run your MVC app again and you should be redirected to your VM for authentication and then back to your app again (but this time using https).
If you are using the default MVC template, in the top right corner assuming you have set up the claims correctly, you should see Hi, <user>#<domain>
The main articles that I followed to achieve this are as follows:
http://blogs.rondewit.com/post/MVC-2b-ADFS-20-Federated-Authentication.aspx
http://garymcallisteronline.blogspot.co.uk/2013/01/aspnet-mvc-4-adfs-20-and-3rd-party-sts.html
Below is a list of gotcha's that I hit (in no particular order).
When setting up the relying party trust enter the data manually and ensure you set the Relying part WS-Federation Passive protocol URL and the relying party trust identifiers correctly. The first is simply the https url that ADFS will redirect back to after authentication has completed - https://localhost for example. The second is an identifier used to identify the application that is trying to authenticate. One of the identifiers entered must match the realm attribute of the wsFederation node in your MVC 4 apps web.config.
When logging in the username should be of the form <domain>\<username>
I couldn't get Windows Authentication to work with any browser other than IE. For this set up to work with Chrome I had to change the order of the local authentication types in the web.config of the adfs/ls application so that forms authentication appeared first. To get to this, open up IIS manager on your VM, expand default web site/adfs/ls, right click ls and select explore.
At the time of writing I haven't been able to login with an AD user I created myself - I've probably just not set it up correctly. When setting this up initially, I'd suggest trying to connect with the admin user you created through the azure portal when you created the VM.
Once I finally managed to authenticate correctly AntiForgeryToken html helper started throwing an exception, talking about missing claims. Ensure that you have added a claim rule to your relying party trust, that sets either the name or name id claim. Then in Application_Start do the following: AntiForgeryConfig.UniqueClaimTypeIdentifier = ClaimTypes.Name; as explained here.
It is also worth noting that the Identity and Access tool allows you to setup authentication with Azure ACS and more noteworthy, a development STS. For my requirements, I need to be able to integrate with ADFS, but if you're just experimenting with claims based authentication, one of these may be a better option than the process that I have gone through above.
Consider ADFS and ws-federation.
Ws-federation is an enterprise sso protocol that gives you cross domain authentication/authorization in a sso manner. Adfs is a free implementation of the protocol that sits on top of the active directory. It is relatively easy to set up.
But having a client application that expects a ws-federation identity provider, you can substitute the provider with any compliant provider, your own or the identityserver which is another free implementation but can use a membership provider. The completely custom implementation on the other hand would give you a chance to set up and serve an
arbitrary identities.
The is a small learning curve for this approach but benetifs are:
cross domain sso
support for multiple browsers for free (kerberos/ntlm based ad authentication could be unsupported on some browsers)
works in an intranet and the internet
support for advanced scenarios like for example you can set up your cloud Office365 to authenticate against your local adfs
adfs 2.0 is free component dowloadable from msdn
This will probably turn out to be a doozie.
I'm developing an application in ASP.NET to be put on our company's intranet site. I've been handed a specification in regards to security and have no idea how to do it.
First part: The application is to use Windows Authentication. This part seems easy enough; I opened IIS in Administrative Tools, right clicked the node of my website, properties and checked 'Integrate Windows Authentication'. However, I have no idea how I will govern which people have access to my site. I'm thinking this should be taken care of at the database level. This is Q#1
Second part -- I have to implement a process for the following scenario: User 'Jane' can log in to our network, but does not have rights to my application. User 'Bob' does have rights to use my application. Bob needs to be able to sit at Jane's computer (under her network account), but be able to enter his credentials into my application and use it (even though Jane is logged into the local machine and network). This is Q#2
Any help, general direction, or advice would be appreciated. The winning lottery numbers would be appreciated even more.
Thanks,
Jason
You're looking for Windows Authentication and Authorization in ASP.NET
How To Use Windows Auth in ASP.NET
Authentication/Authorization Explained
How To Implement Windows Auth in ASP.NET
Part 2...you're right, that's tough. You'll need to roll your own custom security provider.
You'll have a login page, then check that against Active Directory yourself. From MSDN
ASP.NET also supports custom solutions
for using Windows authentication,
which bypasses IIS authentication. For
example, you can write a custom ISAPI
filter that checks the user's
credentials against Active Directory.
With this approach you must manually
create a WindowsPrincipal object.
You've got requirements around authentication and authorization here.
Authentication: The act of confirming identity
Authorization: The act of correlating an identity to a privilege (eg Read/Write/Delete)
Windows Authentication is useful if you want "auto-signon" capability. The site will "know" the user by ID without them having to sign in.
The need for users to login from multiple locations means that you must implement a login page. This would fulfill your requirement in which one user may sit at another's workstation and log in.
You will want to authenticate users against the Windows domain. This can be done with a custom membership provider. Here's a walkthrough:
http://msdn.microsoft.com/en-us/library/ms180890(v=vs.80).aspx
This will allow you to present a login page that will authenticate users with their domain username and password. This will authenticate users- the identity of the user will be stored in the HttpContext.User. You can then also maintain a user list in a database to store authorization data.
Also found this -- a pretty good resource for anybody out there who's in the same boat:
Mixing Forms and Windows Security in ASP.NET
http://msdn.microsoft.com/en-us/library/ms972958.aspx
I have a website with a large user base configured with asp.net 2.0 forms authentication. Before the user logs in via forms authentication is it possible to retrieve the windows login name/user account name on the machine they are using?
Many thanks
It certainly is possible--by adding another web application to your system. Here's roughly how I have done it:
Your primary web app uses Forms authentication. On the forms login page, any user that is determined to be on the local LAN (check IP address), redirect them to another app that uses Windows authentication. In this second app, you can determine the user (assuming the browser is configured to send credentials automatically to the zone in which your app resides), then set a cookie which your first app can read, and redirect the user back to the original app.
This does work.
This would only be possible if you were using Windows Authentication in your web application and then only if the user had logged in.
The kind of information you are after is not sent as part of the web request (quite rightly) and is therefore unknown to the web server.
Unfortunately no - if the user has not logged on, they are browsing anonymously, and are therefore unknown to the server. There is no way to identify them.
Once they're logged on, if you're using impersonation use WindowsIdentity.GetCurrent().Name. However, for forms authentication there's no direct way to ask the browser for their Windows credentials as they may not even be running Windows!
Not BEFORE no (not from the server).
Depending on the type of Auth you use, though, and the way the site is configured, you CAN get them to log in with their windows details.
See Mixing Forms and Windows Security in ASP.NET on Microsoft's MSDN.
The main difference with #TheObjectGuy answer is that instead of using 2 websites, this does all in a single website by configuring IIS to use the Integrated Windows authentication just in a "single" page (WinLogin.aspx).
My supervisor at the office tells me that he saw a demonstration with a pre-release version of Microsoft "Geneva" (now Windows Identity Foundation) where a developer did the following:
He set up some sort of ASP.net web application where a user could log in using a customized log-on system. Behind the scenes, the web application logs the user in as a user in an Active Directory.
The user logs in.
Once the user is logged in, the the ASP.net web application thread runs as the logged in user for the duration of the user's session and can access resources on the network (such as running SQL queries on tables whose access is controlled Active Directory)
Steps 2) and 3) are exactly the same as using the "Integrated Windows Authentication" setting in the "Directory Security" tab of the web site settings in IIS. Step 1) is different because we are using a custom log-on system as opposed to the Kerberos authentication.
We want to set up one of our applications to operate exactly as described in 1), 2), and 3). However, all the documentation that I've seen regarding Windows Identify Foundation is about Cardspace and Federated Security. We have zero interest in using either of these technologies right now.
We just want to be able to log users in to Active Directory Accounts behind the scenes.
Yes, we've tried the ActiveDirectoryMembershipProvider with Forms Authentication, but it's a complete kludge to actually access resources on the network requiring impersonation on every page!
UPDATE Jan 7, 2010. Okay, I've been working at this for a while, and everything I've managed to come up falls short of what I want to achieve. Perhaps the functionality I want is not in the release version of WIF.
Here's where I'm at now. I've found some documentation on MSDN that indicates that there are three different identities used in ASP.net: the identity specified by HttpContext.Current.User, the identity specified by Thread.CurrentPrincipal, and finally the identity specified by WindowsIdentity.GetCurrent. link
In one example of where I want to use the process I'm looking to design, I want to perform a SQL query as the logged in user. In my debugger, I see that I easily set the HttpContext and Thread users to the logged in user. However, when I connect to the SQL server using Windows Authentication, it always always always connects as the WindowsIdentity.GetCurrent user and that user is always always always the identity of the ASP.net process unless I'm using Windows Authentication with impersonation. I absolutely cannot use Windows Authentication with my application because my users must log in by playing a magic flute song and Windows Authentication has no support for logging in with magic flute songs.
To clarify, there is no trouble with obtaining a WindowsIdentity representing the logged in user (who logged in with a magic flute song). The problem is that I cannot use that WindowsIdentity to perform SQL queries for my user.
WIF allows you to configure it so a claims based identity maps to an AD account, the claim may either be a federated identity claim, or delivered via an information card. c2WTS performs this function.
Even when it does map because of delegation you're always going to have to delegate if you want to use the AD identity IIS is impersonating - that's just how it works, unless you setup Kerberos delegation for IIS
You can achieve the same using Identity Impersonation in ASP.net. Also you need to enable windows integrated authentication for you web app. This will solve the purpose. If the logged in user does not have the required rights to access resources you will get security exceptions which you will have to handle.
