.net core identity 2.1 role authorize not working

Question

I've implemented role based auth several times pre 2.1. Followed the steps to scaffold the new 2.1 identities.

I extended the IdentityUser model to add additional fields, login works fine, new fields are present.

startup.cs configure services contains

         services.AddDefaultIdentity<AppUser>()
            .AddRoles<IdentityRole>()
            .AddEntityFrameworkStores<ApplicationDbContext>();

I seeded the roles

         IdentityRole role = new IdentityRole();
         role.Name = "Administrator";
         IdentityResult roleResult = roleManager.
         CreateAsync(role).Result;

Then created a user and added to the role

        AppUser user = new AppUser();
        user.UserName = "Admin";
        user.Email = "[email protected]";
        user.Name = "Administrator";
        user.LockoutEnabled = false;
        user.EmailConfirmed = true;

        IdentityResult result = userManager.CreateAsync(user, "password").Result;

        if (result.Succeeded)
        {
            userManager.AddToRoleAsync(user, "Administrator").Wait();
        }

Everything succeeded, and the database looks fine (AspNetUserRoles has links)

However, decorating a controller with a role will always return not authorized

       [Authorize(Roles = "Administrator")]

But, a simple login check with [Authorize] (no role) will work.

How might I fix this/what is the easiest way to incorporate the source code so I can step through/debug the [Authorize] tags?

How to fix

However, decorating a controller with a role will always return not authorized

  [Authorize(Roles = "Administrator")]

It's a known bug in the version of 2.1 . See issue here .

I follow the advice of using the old api suggested by HaoK and C-BERBER , and it now works flawlessly .

Here's my DbContext:

public class ApplicationDbContext : IdentityDbContext<AppUser,IdentityRole,string>
{
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
        : base(options)
    {
    }
}

Configure the identity using the old-style api :

services.AddIdentity<AppUser, IdentityRole>()
        .AddRoleManager<RoleManager<IdentityRole>>()
        .AddDefaultUI()
        .AddDefaultTokenProviders()
        .AddEntityFrameworkStores<ApplicationDbContext>();

Lastly , logout and re-signin , it will work as expected now .

How to Debug source code

I guess you won't want to debug the AuthorizeAttribe itself , since it is processed at compile-time . If you mean to debug the AuthorizeFilter , you can follow the steps as below :

click Tools -> Options -> Debugging

1. within General , unselect the Enable Just My Code in Visual Studio
2. select Enable Source Link Support
3. within Symbols , make sure that the Microsoft Symbol Servers is selected

And you can debug the source code now . However , due to the way that filter works , you need set a breakpoint before MVC . I just set a dummy middleware that will take place before the MVC router handler :

Answer 2

In my case of ASP.NET Core 3 (preview) + Angular, solution was in AddAuthentication

services.AddDefaultIdentity<ApplicationUser>()
    .AddRoles<IdentityRole>()
    .AddRoleManager<RoleManager<IdentityRole>>()
    .AddEntityFrameworkStores<ApplicationDbContext>();

services.AddAuthentication(options =>
{
    options.DefaultAuthenticateScheme = IdentityConstants.ApplicationScheme;
    options.DefaultChallengeScheme = IdentityConstants.ApplicationScheme;
    options.DefaultSignInScheme = IdentityConstants.ExternalScheme;
});
