Tuhin Paul · Answer

Hello Neeraj, Basic steps to implement LDAP authentication: 1. Add a reference to the System.DirectoryServices assembly in your project. 2. Modify the web.config file to include the following configuration settings 3. In the Login action of your controller, use the DirectoryEntry class to authenticate the user [HttpPost] public ActionResult Login(LoginViewModel model, string returnUrl) { if (ModelState.IsValid) { try { using (var entry = new DirectoryEntry("LDAP://yourdomain.com", model.UserName, model.Password)) { var search = new DirectorySearcher(entry) { Filter = "(&(objectClass=user)(sAMAccountName=" + model.UserName + "))" }; SearchResult result = search.FindOne(); if (result != null) { // User authenticated successfully, redirect to the home page FormsAuthentication.SetAuthCookie(model.UserName, false); return RedirectToAction("Index", "Home"); } } } catch (Exception ex) { ModelState.AddModelError("", "An error occurred while trying to authenticate. Please try again later."); } } // Authentication failed, show the login page again return View(model); } 4. Create a Login view that includes fields for the username and password.
