Hi Experts,<br />
we have an ASP.Net C# webForms site, and &nbsp;we have been requested to validate users in current Active Directory:<br />
- If the user was authenticated in the AD, He or She should not see the Login Form. <br />
- If the user did not authenticate in AD, then He or She has to see the login WebForm.<br />
<br />
I have searched the Internet looking for working examples about it but most of them are MVC and those tutorials does not work for our development team because we are developing using WebForms. Can you please link examples or provide guidance on how to make this work?<br />
Thanks a lot!

ASP.Net C# Authenticate user in Active Directory

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

ASP.NET

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.
