如何将IdentityServer4身份映射到任何WebApp（.Net MVC Boilerplate，.Net Core Boilerplate）

Question

我正在创建一个SSO服务器，以将所有用户集中在ActiveDirectory（AD）中，并在那里管理它们，而不是每个特定应用程序的数据库。

为了制作此服务器，我使用了带有Ldap / AD扩展名的 IdentityServer4（Idsr4）

我已将Idsr4设置为使用基于AD的身份（这是“集中身份”），并且用户现在可以使用自己的AD登录名/密码登录Idsr4

现在的问题是如何将集中式身份映射到应用程序。我想在多个应用程序中使用同一身份用户。

我通读了IdentityServer4的文档，但找不到与建议的结构相关的任何内容。

是否有人有清晰的结构设置可用于了解整个设置？（如Asp.Net MVC Boilerplate，IdentityServer4，Protected Api之类的分隔。）

IdentityServer4配置：

 public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc();

        // configure identity server with in-memory stores, keys, clients and scopes
        services.AddIdentityServer()
            .AddDeveloperSigningCredential()
            ////.AddSigningCredential(...) // Strongly recommended, if you want something more secure than developer signing (Read The Manual since it's highly recommended)
            .AddInMemoryIdentityResources(InMemoryInitConfig.GetIdentityResources())
            .AddInMemoryApiResources(InMemoryInitConfig.GetApiResources())
            .AddInMemoryClients(InMemoryInitConfig.GetClients())
            .AddLdapUsers<OpenLdapAppUser>(Configuration.GetSection("IdentityServerLdap"), UserStore.InMemory);
    }

IdentityServer4 InMemoryInitConfig：

namespace QuickstartIdentityServer{
public class InMemoryInitConfig
{
    // scopes define the resources in your system
    public static IEnumerable<IdentityResource> GetIdentityResources()
    {
        return new List<IdentityResource>
        {
            new IdentityResources.OpenId(),
            new IdentityResources.Profile(),
        };
    }

    public static IEnumerable<ApiResource> GetApiResources()
    {
        return new List<ApiResource>
        {
            new ApiResource("api1", "My API")
        };
    }

    // clients want to access resources (aka scopes)
    public static IEnumerable<Client> GetClients()
    {
        // client credentials client
        return new List<Client>
        {

            //DEMO HTTP CLIENT
            new Client
            {
                ClientId = "demo",
                ClientSecrets = new List<Secret> {new Secret("password".Sha256()) } ,
                ClientName = "demo",
                AllowedGrantTypes = {
                    GrantType.ClientCredentials, // Server to server
                    GrantType.ResourceOwnerPassword, // User to server
                    GrantType.Implicit
                },

                //GrantTypes.HybridAndClientCredentials,
                AllowAccessTokensViaBrowser = true,

                AllowOfflineAccess = true,
                AccessTokenLifetime = 90, // 1.5 minutes
                AbsoluteRefreshTokenLifetime = 0,
                RefreshTokenUsage = TokenUsage.OneTimeOnly,
                RefreshTokenExpiration = TokenExpiration.Sliding,
                UpdateAccessTokenClaimsOnRefresh = true,
                RequireConsent = false,

                RedirectUris = {
                    "http://localhost:6234/"
                },

                PostLogoutRedirectUris = { "http://localhost:6234" },
                AllowedCorsOrigins ={ "http://localhost:6234/" },

                AllowedScopes =
                {
                    IdentityServerConstants.StandardScopes.OpenId,
                    IdentityServerConstants.StandardScopes.Profile,
                    "api1"
                },

            },



        };
    }
}

}

我的客户端配置：

public void Configuration(IAppBuilder app)

    {

        app.UseAbp();

        app.UseOAuthBearerAuthentication(AccountController.OAuthBearerOptions);

        // ABP
        //app.UseCookieAuthentication(new CookieAuthenticationOptions
        //{
        //    AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
        //    LoginPath = new PathString("/Account/Login"),
        //    // evaluate for Persistent cookies (IsPermanent == true). Defaults to 14 days when not set.
        //    //ExpireTimeSpan = new TimeSpan(int.Parse(ConfigurationManager.AppSettings["AuthSession.ExpireTimeInDays.WhenPersistent"] ?? "14"), 0, 0, 0),
        //    //SlidingExpiration = bool.Parse(ConfigurationManager.AppSettings["AuthSession.SlidingExpirationEnabled"] ?? bool.FalseString)
        //    ExpireTimeSpan = TimeSpan.FromHours(12),
        //    SlidingExpiration = true
        //});
        // END ABP

        /// IDENTITYSERVER
        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = "Cookies"
        });

        app.UseOpenIdConnectAuthentication(new OpenIdConnectAuthenticationOptions
        {
            Authority = "http://localhost:5443", //ID Server
            ClientId = "demo",
            ClientSecret = "password",
            ResponseType = "id_token token",
            SignInAsAuthenticationType = "Cookies",
            RedirectUri = "http://localhost:6234/", //URL of website when cancel login on idsvr4
            PostLogoutRedirectUri = "http://localhost:6234", //URL Logout ??? << when this occor
            Scope = "openid",
            RequireHttpsMetadata = false,

            //AuthenticationMode = Microsoft.Owin.Security.AuthenticationMode.Active,

        });
        /// END IDENTITYSERVER

        app.UseExternalSignInCookie("Cookies");

        app.MapSignalR();
    }

我在阅读有关OpenID Connect的文档时，发现可以为httpContext创建通知，以便在Idsrv4 userinfo端点中接受用户的声明，如下所示：

public void Configuration(IAppBuilder app)

    {

        app.UseAbp();

        // ABP
        //app.UseOAuthBearerAuthentication(AccountController.OAuthBearerOptions);

        //app.UseCookieAuthentication(new CookieAuthenticationOptions
        //{
        //    AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
        //    LoginPath = new PathString("/Account/Login"),
        //    // evaluate for Persistent cookies (IsPermanent == true). Defaults to 14 days when not set.
        //    //ExpireTimeSpan = new TimeSpan(int.Parse(ConfigurationManager.AppSettings["AuthSession.ExpireTimeInDays.WhenPersistent"] ?? "14"), 0, 0, 0),
        //    //SlidingExpiration = bool.Parse(ConfigurationManager.AppSettings["AuthSession.SlidingExpirationEnabled"] ?? bool.FalseString)
        //    ExpireTimeSpan = TimeSpan.FromHours(12),
        //    SlidingExpiration = true
        //});
        // END ABP

        /// IDENTITYSERVER
        AntiForgeryConfig.UniqueClaimTypeIdentifier = Thinktecture.IdentityModel.Client.JwtClaimTypes.Subject;
        JwtSecurityTokenHandler.DefaultInboundClaimFilter.Clear();

更新2

谢谢@Khanh TO，

我按照您的建议做了，我保留了每个应用程序的数据库

但是，为了不再通过应用程序数据库管理用户，我对从idsr4 userinfo端点获取的方法进行了硬编码

在abpUsers表中创建或更新用户所需的信息，然后应用程序解释数据并执行必要的操作

更具体地说：在“ redirect_uri我发送给AccountController我的客户的”中，我有一个ActionResult完成所有此工作的工作，调用了必要的方法来在客户userstable上创建/更新用户

我认为GrantType.ResourceOwnerPassword流程不支持AD登录，也不支持UseOpenIdConnectAuthentication两者，您可以使用Implicit或Hybrid流程。
在对客户端mvc应用进行身份验证之后，您可以查看中的任何声明，HttpContext.User 并以用户身份找到正确的声明值（它们只是声明，而无需创建本地帐户）
