I have a Silverlight 4 application that uses RIA services and Windows Authentication. I am trying to make it so that if authentication fails the user gets redirected to a login page. I cannot get the login page to authenticate the user's username and password because "Windows authentication does not support logging in."
Does anyone know how to authenticate a user's windows account via a custom login page using RIA services and the Authentication Service?
Thanks in advance!
Excuse my bad english.
Well, i had the same problem, but i looked this video and find one way to implement a windows authentication login with Silverlight 4.

I'm creating a small web app running on IIS and I need to implement a secure way to handle login authentication against active directory.
Currently, I have it set up with Windows authentication, so when users first go to the website it shows the login prompt from the browser, they login using their AD credentials, and then it allows them into the site.
However, I want to have an actual login page and have these credentials validated against AD instead of Windows Authentication. I've been researching for hours about LDAP but I can't seem to find good documentation/videos on how to set it up to communicate with AD. I've thought about using 3rd party services like Okta but I don't think I need to.
Does anyone have any ideas?
I am trying to set up a .Net Core 3.0 Web API and Angular application using AzureAD for authentication, all seems good except for an error I am getting when the Client tries to call the web API (see below).
I hit the angular application and successfully authenticate with AzureAD, I have followed all the instructions for exposing the API and granting permissions but no joy. I wrote another test application with 2.2 and that worked fine.
Anyone having a similar issue?
Thanks, Mike
“AADSTS65001: The user or administrator has not consented to use the application with ID ‘f1be5414-b865-4fb4-9943-6dfc66c8fdcf’ named ‘MW Front End Auth Test’.

The issue is clear, consent required.
You can force user consent through a URL request, the url will look like:
https://login.microsoftonline.com/<tenant-id>/oauth2/authorize?client_id=<client id>&response_type=code&redirect_uri=<Your-Redirect-URI-Https-Encoded>&nonce=1234&resource=<your-resource-Https-encoded>&prompt=consent
If it needs admin consent, use $prompt=admin_consent instead.(need to use admin account to sign in)
I'm developing an Enterprise/Internet Application with WebAPI 2 RESTful server and SPA web client (Angular2) —So I have two separated projects created using ASP.NET 4.6 Empty template and both use OWIN and are IIS hosted.
The requirement for Authentication is:
Active Directory user which is logged in to the workstation will authenticated automatically once she opens any page from app in the browser if user id/name found in the database, with no need to enter her user/pass. Let name this as auto-login. Else if it's not found in the DB it will redirected to the login page.
Also there should be a logout option which redirects user to the login page after logging she out.
In the login page any AD user can enter her/his AD user&pass and after successful check against database (existed) and AD (valid credential) she/he will logged in to the system (Obviously it may be different than user currently is logged in to the workstation)
In addition to the web client it will have other clients such mobile apps which will connect and be served by the WebAPI back-end. Users will login there using their AD user & pass too. Let name it manual-login.
According to the REST architecture and having both AD enterprise and internet/mobile users together, the authentication should be token based —this is what I found till now but I'm not sure.
I read about OWIN Authentication architecture and Windows Authentication and I checked MixedAuth, Now I think it is the nearest solution for this requirement as it lets app-defined users to authenticate side by side of windows/AD users. But even after dig into it and its SPA sample I didn't found my way yet and confused.
Anyone can help?
What should I actually do on the WebApi server and SPA Client to accomplish those authentication requirements?
Which middlewares should I add and how should config/manipulate them?
UseCookieAuthentication ?
UseExternalSignInCookie ?
UseOAuthBearerTokens ?
Can I rely just on Bearer tokens (using OAuthBearerTokens MW) and get same token for authenticated windows users to unify authentication model based on bearer tokens? If so, how?
How and where should I put my code for checking that AD user exists in the DB and if not so reject the authentication?
Thanks a lot.
I am developing a intranet web application using ASP.NET MVC 4 that uses Windows-Authentication. I have integrated SharpSVN to do some SVN interactions and initially I was planning to use the username and the password from Windows Authentication, to authenticate the user on SVN, but as I found out, you can't get the password of the user when using Windows Authentication.
So is there any way to achieve this? To make SharpSVN use the Windows Authentication from the ASP.NET?
Thank you.
Look into identity inpersonation this will let you run each windows authenticated user in a thread under that user account. This will mean, that your clients must use machines that belong to the same AD domain as the Web server and as the SVN server.
I'm developing an ASP .NET application, nothing fancy just another LOB App.
Our company's authentication model is based on a typical AD setup. Nearly all of our applications are written on Sharepoint so it is a requirement that the authentication is "automatic", meaning that once you are logged on your machine you have access to all your applications without writing another user or pwd.
For some reasons i cannot develop this app over Sharepoint.. so, the question is How Can I Automatically Authenticate AD users on my web App?
thanks in advance
You need to enable Windows Authentication on the web app. This article has enough details to get you started.
PrincipalContext Authenticator = new PrincipalContext(ContextType.Domain, 'yourDomainName');
AuthenticationFailed = !Authenticator.ValidateCredentials(Username, Password);
If AuthenticationFailed; you can redirect to login page..
