User Identity using Active Directory on Asp.Net MVC(.net framework)

Hi Jaraj

Let me share my current logic, because i am now getting 401 Unauthorized. Maybe i am missing something, username and password are correct i am using them for our AD account. 

// web.config

  
    
    
    
    
	  
	  
	  
	  
	  
  


// controller
 //GET:Login
        public ActionResult Login()
        {
            return View();
        }

        //POST: Login
        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Login(LoginModel login)
        {
            if(ModelState.IsValid)
            {
                // validate credits via AD Account
                bool isAuthenticated = ValidateCredentials(login.UserName, login.Password);

                if(isAuthenticated)
                {
                    // return successful, redirect to the dashboard.
                    TempData["SuccessMessage"] = "Login successful!";
                    return RedirectToAction("Dashboard", "Home");
                }else
                {
                    ModelState.AddModelError("", "Invalid username or password");
                }
            }
            return View(login);
        }

        // validate user account from AD(Active Directory) .
        private bool ValidateCredentials(string password, string username)
        {
            // validate credentials against AD Account.
            using(PrincipalContext pc = new PrincipalContext(ContextType.Domain))
            {
                return pc.ValidateCredentials(username, password);
            }
        }

        //GET: GetLoggedInUser.
        [Authorize(Roles = "Admin")]
        public JsonResult GetLoggedInUser()
        {
            // fetch the logged in user's username.
            string username = User.Identity.Name;
            return Json(new { Username = username }, JsonRequestBehavior.AllowGet);
        }


// view.cshmtl
@model CVResumeScanning.Models.LoginModel

@{
    ViewBag.Title = "Login Home Page";
}

@using (Html.BeginForm("Login", "Account", FormMethod.Post, new { id = "loginForm" }))
{
    @Html.AntiForgeryToken()
    

        

            
            

                
            

            
            

                @Html.LabelFor(model => model.UserName, htmlAttributes: new { @class = "col-md-4 col-form-label text-md-right" })
                

                    @Html.EditorFor(model => model.UserName, new { htmlAttributes = new { @class = "form-control" } })
                    

                        @Html.ValidationMessageFor(model => model.UserName, "", new { @class = "text-danger" })
                    
                
            
            

            
            

                @Html.LabelFor(model => model.Password, htmlAttributes: new { @class = "col-md-4 col-form-label text-md-right" })
                

                    @Html.PasswordFor(model => model.Password, new { @class = "form-control" })

                    
                    

                        @Html.ValidationMessageFor(model => model.Password, "", new { @class = "text-danger" })
                    
                
            

            

            
            

                

                    Login
                
            
        
    
}

To achieve user identity integration with Active Directory in an ASP.NET MVC application, you can leverage Windows Authentication and the System.DirectoryServices.AccountManagement namespace in C#. Here's a high-level overview of the steps involved:

1. Configure Windows Authentication in your ASP.NET MVC application.
2. Use PrincipalContext to interact with Active Directory for user information.
3. Retrieve the current user's details dynamically from Active Directory.
4. Implement the logic to prompt the Administrator with their AD username during registration.
5. Redirect the Administrator to the dashboard (View.cshtml) for CRUD operations on new users.

While there might not be a specific example that matches your exact requirements, you can refer to Microsoft's documentation on Windows Authentication in ASP.NET and the System.DirectoryServices.AccountManagement namespace for guidance. Additionally, you can adapt and customize existing examples to suit your specific needs for the in-house project.
