ASP.NET Identity check user roles is not working

In that case you need to logout and login the user again.

Because the roles data is also stored in cookies, So you must issue the cookie again to work it.

There seems to be an issue. [The issue by design]

• The role names are case sensitive in AuthorizeAttribute and User.IsInRole
• The role names are case insensitive in UserManager.IsInRole

Moreover, check for the correct role name is used for the verification.

[The above is based on the test performed with below code. Role Name="Admin", User is added to Role "Admin".]

[Authorize(Roles="Admin")] /*True as "Admin" has A capital as entered in Role name*/
public ActionResult Secured()
{
    if (User.IsInRole("admin")) /*This is False*/
    {
         Console.WriteLine("In");
    }
    if(UserManager.IsInRole(User.Identity.GetUserId(), "admin")) /*This is True!!*/
    {
         Console.WriteLine("In");
    }
    return View();
}

If we change the attribute to [Authorize(Roles="admin")], it redirects to Login page.
