I have a claim rule in ADFS 2.0 for a relying party. The rule basically checks if the user is in an AD group. Is it possible in ADFS to specify a custom error page, say "Unauthorized", such that when a user, who is not in the AD group as mentioned in the rule, is redirected to a custom unauthorized error page?
This is supported in 2012R2 where you can add per-RP custom authorization messages. Within this, you can add messages with a link for remediation. See "Customer a relying party authorization message" at ADFS Error page.
You can customize in ADFS 2.0, but would have to look at the error.aspx page and right code for it. I believe you get the RP ID in the error page and you can take action on it in code.
Thanks

My end goal is to register my API to receive notifications of leads generated by LinkedIn for my business's Company Page. The docs here say I need to register at https://api.linkedin.com/v2/leadNotificationUrls using the r_ads_ge_automation permission. I'm trying to acquire this type of access token by using a web browser to hit https://www.linkedin.com/oauth/v2/authorization?response_type=code&client_id=client_id_for_my_application&redirect_uri=https://my.company.net/api/oauth/linkedin&state=Testing12345&scope=r_ads_leadgen_automation, then logging in as a user that is an admin for the respective company page, then acquiring authentication code, and finally requesting an access token.
The problem is that when I try to hit https://www.linkedin.com/oauth/v2/authorization (with the query params above), I get an error response stating "r_ads_leadgen is not authorized for your application". I can't find any kind of application configuration that is supposed to give this permission to my application.
Can anyone help? Thank you

I am working with the functionality to integrate ADFS login page with my application.
Flow
User will try to visit page. Here system will try to authenticate user.
System will redirect user to ADFS login page.
User will enter login information. If user is authenticated then user will be redirected back to the application with authorized token information.
I am facing difficulties to read the token information when the page is redirected back.
I tried
I am able to redirect page to ADFS login page and also can redirect back to my system if the user is authenticated using below url format:
https://adfs-domain-name/adfs/ls
Please find the below code snippet which I am using after getting back the page to read token information.
ClaimsPrincipal claimsPrincipal = Thread.CurrentPrincipal as ClaimsPrincipal;
bool IsAuthenticated = claimsPrincipal.Identity.IsAuthenticated;
int ClaimCount = claimsPrincipal.Claims.Count();
Here I am getting IsAuthenticated as false and ClaimCount as 0 result.
Is there anything incorrect in my code or way to connect ADFS login page ?
Can anyone help me to fix this ?
Please let me know if you have any concern or query or if I am missing something.
In short, I would recommend following this tutorial:
https://learn.microsoft.com/en-us/windows-server/identity/ad-fs/development/enabling-openid-connect-with-ad-fs-2016
I followed the steps in there and got it to work (using OAuth2 / OpenID connect). There are some other interesting resources on that site, too.
Some more pointers:
1) For using OAuth2 the login URL on the ADFS server should be something like:
https://adfs.contoso.com/adfs/oauth2/authorize?[parameters]
The URL parameters are nicely documented here:
https://learn.microsoft.com/en-us/azure/active-directory/develop/active-directory-protocols-oauth-code
2) You can then use the ADAL libraries for the frontend and backend code. In essence, the frontend code will put together the aforementioned login URL and keep the token in the browser's session storage to be sent with each request. The backend library will verify and decode the tokens (into ClaimsPrincipal) for you. You can find the appropriate library components here:
https://learn.microsoft.com/en-us/azure/active-directory/develop/active-directory-authentication-libraries
Ah, yeah, I know these components and docs describe Azure AD (ADFS in the cloud), but what they run there is essentially the same as ADFS 4.0 on Windows Server 2016.
I have an Asp.Net application that communicate with ADFS(on some other Windows Server) for authentication purpose. Currently, when we navigate to application, it redirects to ADFS SSO authentication page. I followed this blog to implement SSO and have some questions here:
Can we change implementation so that it may redirect to authentication page only when I press login button ?
Can we change implementation so that only one page/URL of my application can be accessed without any authentication ?
What parameters are returned when user is authenticated and redirected back to landing page. How do we get all available parameters ?
In this blog returning things are are Value, ValueType, Subject Name, Claim Issuer and Claim Issuer type. Can I get email or username ? so that I may link that person to a client in my application.
If anyone of above is possible, how I can get it ?
The login button is part of the ADFS screen. That's by design. The sample uses WIF so you are outsourcing authentication to ADFS.
Yes - Use the "location" annotation in the web.config. refer Location Element.
The parameters that are returned are the claims configured in the claims rules. The article show "Display-Name" and UPN. If you want email, just add another row and select it from the dropdown.
I've successfully installed and tested the OAuth 2 workflow with Symfony 2 and FOSOAuthServerBundle.
I can request a code, and get a pair of access/refresh token successfully from a "login with" button on a third party test page i've set up and retrieve a user from my API through a custom API call. Pretty cool here.
However, each time I test the flow from the beginning, my oAuth server keeps on redirecting the user on the authorization page. Here are my questions.
Once a user has authorized and app, shouldn't the authorization part of the process be skipped with OAuth 2.0 ?
Is that fixed on the server side or should i change the way i request the credentials on client site ?
And finally... could i debug and fix this ?
If anyone struggles again, the solution is here :
https://github.com/FriendsOfSymfony/FOSOAuthServerBundle/blob/master/Resources/doc/the_oauth_event_class.md
This feature is not default in FOSOAuthServer bundle. You have to create and EventListener and check client or user status, save the user's choice, and [quote:even bypass the authorization process].
In my MVC 5 application I have applied some Role filters such as:
[Authorize(Roles = "ManageRoles")]
Now if a user does not have permission to access this role, it redirects me to the login page. This is incorrect in my application as I want to rather display an error message saying that you donot have permission to access.
Where do I change what happens if a user is not authorised to access a filter?
Do I have to implement custom filters? I would like to try and use the redirectTo action if possible so that I can have different error pages in different situations.
Use Custom Authorize Attribure - Ben Scheirman or Ben Cull's answer in this thread.
Also Check Mark's response to similar question, where he used HandleUnauthorizedRequest to redirect unauthorized users.
In the both the above approaches, you can redirect to any Route or Action of your interest and use HttpContent.Items[] or TempData to hold the specific error messages or values to be display on the destination page.
MVC5 has actually started to address this issue. They now include Authentication Filters in addition to Authorization Filters. These are pretty lightly documented, but my gut feeling is that this a first stab at separating authentication from authorization (up until now, ASP.NET has confused the two)
What i'm thinking is that Authentication filters will be used to control whether a user is logged in or not, and Authorization filters will be used to control what you have access to. However, it seems that this isn't yet fully realized.
In your Login view, you can add logic for:
Checking if the request is not authenticated
1.1. Display login form
Checking if the user is authenticated but not in the required role
2.1. Display error message
Since you'll be automatically redirected to the login page by your Web.config settings, you can take advantage of this mechanism.
if (!Request.IsAuthenticated)
{
//render login form
}
else
{
<p>Error: you do not have the necessary credentials to access this resource.</p>
}
Another option would be to create your own AuthorizationAttribute. This question is similar to yours. You might find it useful.
