I have a Blazor WASM project with a Blazor Client and ASP.NET core server. I can authenticate with user/password using the following code:
services
.AddDefaultIdentity<ApplicationUser>(
options => options.SignIn.RequireConfirmedAccount = true)
.AddRoles<IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>();
services
.AddIdentityServer()
.AddApiAuthorization<ApplicationUser, ApplicationDbContext>();
services
.AddAuthentication()
.AddIdentityServerJwt();
services.AddTransient<IProfileService, ProfileService>();
services.AddAuthorization(options =>
{
options.AddPolicy("ApiScope", policy =>
{
policy.RequireAuthenticatedUser();
policy.RequireClaim("scope", "api1");
});
});
When I add the following code, I can successfully authenticate with clientcredentials from a console client. But then the Blazor client user/password authentication stops working.
...
services
.AddIdentityServer()
.AddApiAuthorization<ApplicationUser, ApplicationDbContext>()
+.AddInMemoryApiScopes(Config.ApiScopes)
+.AddClientStore<ClientStore>()
+.AddDeveloperSigningCredential();
services
.AddAuthentication()
.AddIdentityServerJwt();
+services
+ .AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
+ .AddJwtBearer(JwtBearerDefaults.AuthenticationScheme, options =>
+ {
+ options.Authority = "https://localhost:44311";
+ options.TokenValidationParameters = new TokenValidationParameters
+ {
+ ValidateAudience = false,
+ };
+ });
...
In the browser while trying to authenticate in the Blazor client, the console prints:
info: Microsoft.AspNetCore.Authorization.DefaultAuthorizationService[2]
Authorization failed. These requirements were not met:
DenyAnonymousAuthorizationRequirement: Requires an authenticated user.
I have tried a lot, but I'm not able to make both work together. It seems that somehow this configuration requires authentication for everything, even the pages/controllers that are marked AllowAnonymous. So, when I try to authenticate, it gives me an error telling me the user must be authenticated: DenyAnonymousAuthorizationRequirement. The policy, "ApiScope" is only intended for the clientcredentials client, not for the Blazor client. If removed, the RequireAuthenticatedUser call doesn't make a difference, same error.
Any help is appreciated.
