I would like to use ASP.NET Core Identity and IdentityServer together and provide Role-based authorization.
3 projects in the solution:
- ApplicationAPI
- ApplicationWeb
- IdentityServer

Statup.cs in API Client
public class Startup
{
public IConfiguration Configuration { get; }
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public void ConfigureServices(IServiceCollection services)
{
services.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
services.AddControllers();
services.AddAuthentication("Bearer")
.AddJwtBearer("Bearer", options =>
{
options.Authority = "https://localhost:5001";
options.TokenValidationParameters = new TokenValidationParameters
{
ValidateAudience = false
};
});
services.AddAuthorization(options =>
{
options.AddPolicy("ApiScope", policy =>
{
policy.RequireAuthenticatedUser();
policy.RequireClaim("scope", "api1");
});
});
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseHttpsRedirection();
app.UseRouting();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers()
.RequireAuthorization("ApiScope");
});
}
}
Startup.cs in MVC Client
public class Startup
{
public IConfiguration Configuration { get; }
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public void ConfigureServices(IServiceCollection services)
{
services.AddControllersWithViews();
JwtSecurityTokenHandler.DefaultMapInboundClaims = false;
services.AddAuthentication(options =>
{
options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
})
.AddCookie(CookieAuthenticationDefaults.AuthenticationScheme)
.AddOpenIdConnect(OpenIdConnectDefaults.AuthenticationScheme, options =>
{
options.Authority = "https://localhost:5001";
options.ClientId = "mvc";
options.ClientSecret = "secret";
options.ResponseType = "code id_token";
options.Scope.Add("email");
options.Scope.Add("roles");
options.ClaimActions.DeleteClaim("sid");
options.ClaimActions.DeleteClaim("idp");
options.ClaimActions.DeleteClaim("s_hash");
options.ClaimActions.DeleteClaim("auth_time");
options.ClaimActions.MapJsonKey("role", "role");
options.Scope.Add("api1");
options.SaveTokens = true;
options.GetClaimsFromUserInfoEndpoint = true;
options.TokenValidationParameters = new TokenValidationParameters
{
NameClaimType = "name",
RoleClaimType = "role"
};
});
services.AddTransient<AuthenticationDelegatingHandler>();
services.AddHttpClient("ApplicationAPI", client =>
{
client.BaseAddress = new Uri("https://localhost:5002/");
client.DefaultRequestHeaders.Clear();
client.DefaultRequestHeaders.Add(HeaderNames.Accept, "application/json");
}).AddHttpMessageHandler<AuthenticationDelegatingHandler>();
services.AddHttpClient("ApplicationIdentityServer", client =>
{
client.BaseAddress = new Uri("https://localhost:5001/");
client.DefaultRequestHeaders.Clear();
client.DefaultRequestHeaders.Add(HeaderNames.Accept, "application/json");
});
services.AddHttpContextAccessor();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "default",
pattern: "{area=Admin}/{controller=Home}/{action=Index}/{id?}");
});
}
}
AuthenticationDelegatingHandler in MVC Application
To prevent getting token again.
public class AuthenticationDelegatingHandler : DelegatingHandler
{
private readonly IHttpContextAccessor _httpContextAccessor;
public AuthenticationDelegatingHandler(IHttpContextAccessor httpContextAccessor)
{
_httpContextAccessor = httpContextAccessor ?? throw new ArgumentNullException(nameof(httpContextAccessor));
}
protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
var accessToken = await _httpContextAccessor.HttpContext.GetTokenAsync(OpenIdConnectParameterNames.AccessToken);
if (!string.IsNullOrWhiteSpace(accessToken))
{
request.SetBearerToken(accessToken);
}
return await base.SendAsync(request, cancellationToken);
}
}
Config.cs in IdentityServer
public static class Config
{
public static IEnumerable<IdentityResource> IdentityResources =>
new List<IdentityResource>
{
new IdentityResources.OpenId(),
new IdentityResources.Profile(),
new IdentityResources.Email(),
new IdentityResource("roles", "Your role(s)", new List<string>() { "role" })
};
public static IEnumerable<ApiScope> ApiScopes =>
new List<ApiScope>
{
new ApiScope("api1", "My API")
};
public static IEnumerable<Client> Clients =>
// we can remove API client here because we call API from MVC
// and pass the token to API Application.
// Only we get token from IdentityServer with MVC Application
new List<Client>
{
new Client
{
ClientId = "client",
ClientSecrets = { new Secret("secret".Sha256()) },
AllowedGrantTypes = GrantTypes.ClientCredentials,
AllowedScopes = { "api1" }
},
new Client
{
ClientId = "mvc",
ClientName = "Application Web",
AllowedGrantTypes = GrantTypes.Hybrid,
ClientSecrets = { new Secret("secret".Sha256()) },
RequirePkce = false,
AllowRememberConsent = false,
RedirectUris = { "https://localhost:5003/signin-oidc" },
PostLogoutRedirectUris = { "https://localhost:5003/signout-callback-oidc" },
AllowedScopes = new List<string>
{
IdentityServerConstants.StandardScopes.OpenId,
IdentityServerConstants.StandardScopes.Profile,
IdentityServerConstants.StandardScopes.Email,
"api1",
"roles"
}
}
};
}
I added ASP.NET Core Identity in the IdentityServer project
Startup.cs in IdentityServer
public class Startup
{
public IWebHostEnvironment Environment { get; }
public IConfiguration Configuration { get; }
public Startup(IWebHostEnvironment environment, IConfiguration configuration)
{
Environment = environment;
Configuration = configuration;
}
public void ConfigureServices(IServiceCollection services)
{
services.AddControllersWithViews();
services.AddRazorPages()
.AddRazorPagesOptions(options =>
{
options.Conventions.AuthorizeAreaFolder("Identity", "/Account/Manage");
});
services.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
services.AddIdentity<ApplicationUser, ApplicationRole>(options =>
{
options.SignIn.RequireConfirmedEmail = true;
})
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();
var builder = services.AddIdentityServer(options =>
{
options.Events.RaiseErrorEvents = true;
options.Events.RaiseInformationEvents = true;
options.Events.RaiseFailureEvents = true;
options.Events.RaiseSuccessEvents = true;
options.EmitStaticAudienceClaim = true;
options.UserInteraction.LoginUrl = "/Account/Login";
options.UserInteraction.LogoutUrl = "/Account/Logout";
options.Authentication = new AuthenticationOptions()
{
CookieLifetime = TimeSpan.FromHours(10),
CookieSlidingExpiration = true
};
})
.AddInMemoryIdentityResources(Config.IdentityResources)
.AddInMemoryApiScopes(Config.ApiScopes)
.AddInMemoryClients(Config.Clients)
.AddAspNetIdentity<ApplicationUser>();
if (Environment.IsDevelopment())
{
builder.AddDeveloperSigningCredential();
}
services.AddAuthentication()
.AddGoogle(options =>
{
options.SignInScheme = IdentityServerConstants.ExternalCookieAuthenticationScheme;
options.ClientId = "copy client ID from Google here";
options.ClientSecret = "copy client secret from Google here";
});
services.AddTransient<IEmailSender, EmailSender>();
}
public void Configure(IApplicationBuilder app)
{
if (Environment.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseIdentityServer();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
endpoints.MapRazorPages();
});
}
}
