将 Owin.Security.ActiveDirectory 库与 AAD B2C 一起使用是否正确

Is it right way to use Owin.Security.ActiveDirectory library with AAD B2C

我们有两个应用程序通过 "New" 和 "Old" 门户在同一个 AAD B2C 租户中注册。

使用 "Old" 应用程序凭据进行身份验证工作正常。 使用 "New" 应用程序凭据 - 出现错误:

IDX10500: 签名验证失败。无法解析 SecurityKeyIdentifier:'SecurityKeyIdentifier ( IsReadOnly = 假, 计数 = 1, 条款[0] = System.IdentityModel.Tokens.NamedKeySecurityKeyIdentifierClause ) '

使用在 AAD B2C 租户中注册的应用程序使用 Microsoft.Owin.Security.ActiveDirector 库(保护 ASP.Net Web API)的正确方法吗?

P.S。我的问题是基于这个 post.

您只能通过 new Azure portal (portal.azure.com) 中的 Azure AD B2C blade 创建应用程序。

请勿使用经典 Azure 门户 (manage.windowsazure.com) 为 Azure AD B2C 创建应用程序。

如果你想保护 WebApp,你应该使用 Owin 的 OpenIdConnectAuthentication。本文档包含有关如何执行此操作的更多详细信息:Sign-Up & Sign-In in a ASP.NET Web App

如果你想保护 WebAPI,你应该使用 Owin 的 OAuthBearerAuthentication。本文档包含有关如何执行此操作的更多详细信息:Build a .NET web API


WebApp 的示例配置:

public void ConfigureAuth(IAppBuilder app)
{
    app.UseCookieAuthentication(new CookieAuthenticationOptions());
    app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);

    app.UseOpenIdConnectAuthentication(
        new OpenIdConnectAuthenticationOptions
        {
            // Generate the metadata address using the tenant and policy information
            MetadataAddress = String.Format(AadInstance, Tenant, DefaultPolicy),

            // These are standard OpenID Connect parameters, with values pulled from web.config
            ClientId = ClientId,
            RedirectUri = RedirectUri,
            PostLogoutRedirectUri = RedirectUri,

            // Specify the callbacks for each type of notifications
            Notifications = new OpenIdConnectAuthenticationNotifications
            {
                RedirectToIdentityProvider = OnRedirectToIdentityProvider,
                AuthorizationCodeReceived = OnAuthorizationCodeReceived,
                AuthenticationFailed = OnAuthenticationFailed,
            },

            // Specify the claims to validate
            TokenValidationParameters = new TokenValidationParameters
            {
                NameClaimType = "name"
            },

            // Specify the scope by appending all of the scopes requested into one string (separated by a blank space)
            Scope = $"{OpenIdConnectScopes.OpenId} {YourScope1} {YourScope2}"
        }
    );
}

Web 配置示例 API:

    public void ConfigureAuth(IAppBuilder app)
    {
        TokenValidationParameters tvps = new TokenValidationParameters
        {
            // Accept only those tokens where the audience of the token is equal to the client ID of this app
            ValidAudience = ClientId,
            AuthenticationType = Startup.DefaultPolicy
        };

        app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions
        {
            // This SecurityTokenProvider fetches the Azure AD B2C metadata & signing keys from the OpenIDConnect metadata endpoint
            AccessTokenFormat = new JwtFormat(tvps, new OpenIdConnectCachingSecurityTokenProvider(String.Format(AadInstance, Tenant, DefaultPolicy)))
        });
    }
