使用IdentityServer向特定客户端验证特定用户

我正在使用IdentityServerV3来验证少数客户的用户。我在配置IdentityServer时遇到问题,以至于特定的user必须能够登录到特定的`客户端。

让我们采取以下方案:

我有2个客户 - > client1client2。 我有3个用户 - > user1user2user3

user1& user2只能访问client1。而user3只能访问client2

当我尝试使用client1身份登录user3时,身份服务器验证成功。我不想要的。

public static class Clients
{
    public static IEnumerable<Client> Get()
    {
        return new[]
        {
            new Client 
            {
                Enabled = true,
                ClientName = "MVC Client",
                ClientId = "mvc",
                Flow = Flows.Hybrid,

                RedirectUris = new List<string>
                {
                    "https://localhost:44319/"
                }
            },
            new Client 
            {
                Enabled = true,
                ClientName = "MVC Client 2",
                ClientId = "mvc2",
                Flow = Flows.Hybrid,

                RedirectUris = new List<string>
                {
                    "https://localhost:44319/"
                }
            }
        };
    }
}

用户是:

public static class Users
{
    public static List<InMemoryUser> Get()
    {
        return new List<InMemoryUser>
        {
            new InMemoryUser
            {
                Username = "bob",
                Password = "secret",
                Subject = "1",

                Claims = new[]
                {
                    new Claim(Constants.ClaimTypes.GivenName, "Bob"),
                    new Claim(Constants.ClaimTypes.FamilyName, "Smith")
                }
            },
            new InMemoryUser
            {
                Username = "rob",
                Password = "secret",
                Subject = "2",

                Claims = new[]
                {
                    new Claim(Constants.ClaimTypes.GivenName, "Rob"),
                    new Claim(Constants.ClaimTypes.FamilyName, "Thompson")
                }
            },
            new InMemoryUser
            {
                Username = "Jerry",
                Password = "secret",
                Subject = "3",

                Claims = new[]
                {
                    new Claim(Constants.ClaimTypes.GivenName, "Jerry"),
                    new Claim(Constants.ClaimTypes.FamilyName, "Smith")
                }
            }
        };
    }
}

现在OWIN Startup类是:

public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        app.Map("/identity", idsrvApp =>
            {
                idsrvApp.UseIdentityServer(new IdentityServerOptions
                {
                    SiteName = "Embedded IdentityServer",
                    SigningCertificate = LoadCertificate(),

                    Factory = InMemoryFactory.Create(
                        users  : Users.Get(),
                        clients: Clients.Get(),
                        scopes : StandardScopes.All)
                });
            });
    }

    X509Certificate2 LoadCertificate()
    {
        return new X509Certificate2(
            string.Format(@"{0}\bin\identityServer\idsrv3test.pfx", AppDomain.CurrentDomain.BaseDirectory), "idsrv3test");
    }
}

我不知道IdentityServer如何知道哪个用户与哪个客户端混在一起。我IdentityServer不支持我的情景,或者我错过了什么。

更新

    public class LocalRegistrationUserService : UserServiceBase
    {
        public class CustomUser
        {
            public string Subject { get; set; }
            public string Username { get; set; }
            public string Password { get; set; }
            public List<Claim> Claims { get; set; }
        }

        public static List<CustomUser> Users = new List<CustomUser>();

        public string ClientId { get; set; }

        public override Task AuthenticateLocalAsync(LocalAuthenticationContext context)
        {
            var user = Users.SingleOrDefault(x => x.Username == context.UserName && x.Password == context.Password);
            if (user != null)
            {
                context.AuthenticateResult = new AuthenticateResult(user.Subject, user.Username);
            }

            return Task.FromResult(0);
        }
}

While registering the user i am redirecting him to a controller in Identity Server Host

 public class LocalRegistrationController : Controller
    {
        [Route("core/localregistration")]
        [HttpGet]
        public ActionResult Index(string signin)
        {
            return View();
        }

        [Route("core/localregistration")]
        [HttpPost]
        public ActionResult Index(string signin, LocalRegistrationModel model)
        {
            var ctx = Request.GetOwinContext();
            if (ModelState.IsValid)
            {
                var user = new LocalRegistrationUserService.CustomUser
                {
                    Username = model.Username, 
                    Password = model.Password, 
                    Subject = Guid.NewGuid().ToString(),
                    Claims = new List<Claim>()
                };
                LocalRegistrationUserService.Users.Add(user);
                user.Claims.Add(new Claim(Constants.ClaimTypes.GivenName, model.First));
                user.Claims.Add(new Claim(Constants.ClaimTypes.FamilyName, model.Last));

                return Redirect("~/core/" + Constants.RoutePaths.Login + "?signin=" + signin);
            }

            return View();
        }
    }

startup.cs

 app.Map("/core", coreApp =>
            {
                var factory = new IdentityServerServiceFactory()
                    .UseInMemoryClients(Clients.Get())
                    .UseInMemoryScopes(Scopes.Get());

                // different examples of custom user services
                //var userService = new RegisterFirstExternalRegistrationUserService();
                //var userService = new ExternalRegistrationUserService();

                var userService = new LocalRegistrationUserService();

                // note: for the sample this registration is a singletone (not what you want in production probably)
                factory.UserService = new Registration<IUserService>(resolver => userService);
                factory.ViewService = new Registration<IViewService, CustomViewService>();
                var options = new IdentityServerOptions
                {
                    SiteName = "Identity Server 3",

                    SigningCertificate = Certificate.Get(),
                    Factory = factory,

                    AuthenticationOptions = new AuthenticationOptions
                    {
                        IdentityProviders = ConfigureAdditionalIdentityProviders,
                        LoginPageLinks = new LoginPageLink[] { 
                            new LoginPageLink{
                                Text = "Register",
                               // Href = "~/externalregistration",
                                Href = "~/localregistration",
                                //Href = "localregistration"
                            },
                             new LoginPageLink{
                                Text = "Forgot Password?",
                                Href = "~/forgotpassword",
                                //Href = "localregistration"
                            }
                        }
                    },

                    EventsOptions = new EventsOptions
                    {
                        RaiseSuccessEvents = true,
                        RaiseErrorEvents = true,
                        RaiseFailureEvents = true,
                        RaiseInformationEvents = true
                    }
                };

                coreApp.UseIdentityServer(options);
            });

我需要了解在注册时将user映射到client的最佳方法,并确保用户只能登录到该客户端而不能登录任何其他客户端,即使usernamepassword对于该用户的所有客户端都是相同的。

如果您提供自定义声明,并使用用户有权访问的应用程序/客户端的值application_access,那么该怎么办?哪个可能有很多。您可以在IUserService实施中添加此自定义声明,并按照映射其他用户特定声明的相同方式进行映射。

然后,在您的客户端中,检查该特定声明并检查登录用户是否具有针对该特定客户端的特定值的声明。
