Add Custom Claim Types

Question

New to OWIN authentication and finding it hard to create my own owin claim types.

Heres the thing. I need to add custom claims like "GroupID" so i can easily access it on the different pages.

I did something like this in my Login

public ActionResult Login(LoginViewModel model, string returnUrl) {     UserViewModel userModel = new UserViewModel();     if (!ModelState.IsValid)     {         return View(model);     }      if(CommonHelper.ValidateADUser(model.Username,model.Password))     {          UserViewModel curUser = userModel.GetUserDetails(model.Username);         if (curUser != null)         {             var claims = new List<Claim>();             claims.Add(new Claim(ClaimTypes.WindowsAccountName, curUser.Username));             claims.Add(new Claim(ClaimTypes.Name,curUser.Fullname));             claims.Add(new Claim(ClaimTypes.Role, ""));             claims.Add(new Claim("GroupID", curUser.UserGroupID.ToString()));              var id = new ClaimsIdentity(claims, DefaultAuthenticationTypes.ApplicationCookie);             var ctx = Request.GetOwinContext();             AuthenticationManager.SignIn(id);             return RedirectToAction("Index", "Home");         }     }     else     {         ModelState.AddModelError("", "Invalid login attempt.");     }      return View(model); } 

In my login partial I tried to get the value by doing this

public ActionResult _LoginPartial() {     var identity = (ClaimsIdentity)User.Identity;     TempData["curUserFullName"] = identity.FindFirst(ClaimTypes.Name).Value;      string s= identity.FindFirst("GroupID").Value;     return PartialView(); } 

I can get the username and full name with no problem but group id causes an object null error.

Hoping someone could nudge me to the correct answer.

As I've checked your Code there are no problem in it.

Here's what I want you to do:

Check if the cache was clear. If your cache was not cleared you can clear it like this: CTRL+SHIFT+DELETE

It's because during your login, it will save in cookies and it was not clear, and it happens that the new claim was not save in the cookies.

Or try to check if your UserGroupID has a value.
