Question

我们在同一个AAD B2C 租户中注册了两个应用程序，通过＆＃34; New＆＃34;和＃34;老＆＃34;门户。

使用＆＃34;旧＆＃34;进行身份验证应用凭证工作正常。使用＆＃34; New＆＃34;应用程序凭据 - 出现错误：

IDX10500：签名验证失败。无法解析SecurityKeyIdentifier：＆＃39; SecurityKeyIdentifier （ IsReadOnly = False，计数= 1，子句[0] = System.IdentityModel.Tokens.NamedKeySecurityKeyIdentifierClause ）＆＃39;

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

P.S。我的问题基于post。

您应该只通过new Azure portal (portal.azure.com)中的Azure AD B2C刀片创建应用程序。

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

如果要保护WebApp，则应使用Owin的OpenIdConnectAuthentication 。本文档详细介绍了如何执行此操作：Sign-Up & Sign-In in a ASP.NET Web App

如果您想保护WebAPI，则应使用Owin的OAuthBearerAuthentication 。本文档详细介绍了如何执行此操作：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 API的示例配置：

    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)))
        });
    }

是否正确使用Owin.Security.ActiveDirectory库与AAD B2C
