I have a controller that I want to restrict only to a specific role, let's say admin. After setting a user with the admin role, I can validate that he's on that role using the IsInRoleAsync method (which returns true). When setting the attribute with [Authorize(Roles = "admin")] I get a 404 with that very same user . I'm using bearer tokens (I don't think that is relevant but anyway) and here's what I've done to try debugging:
Controller w/o [Authorize] : the resource is returned. [OK]
Controller with [Authorize] : the resource is returned only when I use the Authentication: Bearer [access token] [OK]
Controller with [Authorize(Roles = "admin")] : even after logging in with the user that has the role set, I get the 404 [NOK]
I don't know if I'm missing some configuration, but here's my ConfigureServices:
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc();
// Add framework services.
services.AddDbContext<ApplicationDbContext>(options =>
{
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"));
options.UseOpenIddict();
});
services.AddIdentity<ApplicationUser, IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();
services.AddOpenIddict(opt =>
{
opt.AddEntityFrameworkCoreStores<ApplicationDbContext>();
opt.AddMvcBinders();
opt.EnableTokenEndpoint("/api/token");
opt.AllowPasswordFlow();
opt.DisableHttpsRequirement(); //for dev only!
opt.UseJsonWebTokens();
opt.AddEphemeralSigningKey();
opt.AllowRefreshTokenFlow();
opt.SetAccessTokenLifetime(TimeSpan.FromMinutes(5));
});
services.AddAuthentication(options =>
{
options.DefaultScheme = OAuthValidationDefaults.AuthenticationScheme;
options.DefaultAuthenticateScheme = OAuthValidationConstants.Schemes.Bearer;
options.DefaultSignInScheme = IdentityConstants.ExternalScheme;
})
.AddJwtBearer(options =>
{
options.Authority = "http://localhost:44337/";
options.Audience = "resource_server";
options.RequireHttpsMetadata = false;
options.TokenValidationParameters = new TokenValidationParameters
{
NameClaimType = OpenIdConnectConstants.Claims.Subject,
RoleClaimType = OpenIdConnectConstants.Claims.Role
};
});
services.Configure<IdentityOptions>(options =>
{
// Password settings
options.Password.RequireDigit = true;
options.Password.RequiredLength = 8;
options.Password.RequireNonAlphanumeric = false;
options.Password.RequireUppercase = true;
options.Password.RequireLowercase = false;
// Lockout settings
options.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(30);
options.Lockout.MaxFailedAccessAttempts = 10;
// User settings
options.User.RequireUniqueEmail = true;
// Add application services.
options.ClaimsIdentity.UserNameClaimType= OpenIdConnectConstants.Claims.Name;
options.ClaimsIdentity.UserIdClaimType = OpenIdConnectConstants.Claims.Subject;
options.ClaimsIdentity.RoleClaimType = OpenIdConnectConstants.Claims.Role;
});
services.AddSingleton(typeof(RoleManager<ApplicationUser>));
// Add application services.
services.AddTransient<IEmailSender, AuthMessageSender>();
services.AddTransient<ISmsSender, AuthMessageSender>();
You likely get a 404 response because Identity - which is automatically configured as the default authentication, sign-in/sign-out and challenge/forbidden scheme by services.AddIdentity() - tries to redirect you to the "access denied page" (Account/AccessDenied by default), that probably doesn't exist in your application.
Try to override the default challenge/forbidden scheme to see if it fixes your issue:
services.AddAuthentication(options =>
{
// ...
options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
options.DefaultForbidScheme = JwtBearerDefaults.AuthenticationScheme;
});
To fix your second issue, make sure the JWT claims mapping feature is disabled. If it's not, the JWT handler will "convert" all your role claims to ClaimTypes.Role, which won't work as you configured it to use role as the role claim used by ClaimsPrincipal.IsInRole(...) (RoleClaimType = OpenIdConnectConstants.Claims.Role).
services.AddAuthentication(options =>
{
options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;
})
.AddJwtBearer(options =>
{
// ...
options.SecurityTokenValidators.Clear();
options.SecurityTokenValidators.Add(new JwtSecurityTokenHandler
{
// Disable the built-in JWT claims mapping feature.
InboundClaimTypeMap = new Dictionary<string, string>()
});
});
