Microsoft Active Directory身份驗證單租戶「Live.com」

Question

我已經實現了AD身份驗證，其中我已通過Client ID，redirectUri和Tenant作爲「Common」。由於我使用Tenant作爲live.com的「普通」用戶，因此允許使用outlook.com，microsoft.com以及學校和辦公室。我希望它僅限於Live.com用戶。

public class Startup 
{ 
    // The Client ID is used by the application to uniquely identify itself to Azure AD. 
    string clientId = System.Configuration.ConfigurationManager.AppSettings["ClientId"]; 

    // RedirectUri is the URL where the user will be redirected to after they sign in. 
    string redirectUri = System.Configuration.ConfigurationManager.AppSettings["RedirectUri"]; 

    // Tenant is the tenant ID (e.g. contoso.onmicrosoft.com, or 'common' for multi-tenant) 
    static string tenant = System.Configuration.ConfigurationManager.AppSettings["Tenant"]; 

    // Authority is the URL for authority, composed by Azure Active Directory v2 endpoint and the tenant name (e.g. https://login.microsoftonline.com/contoso.onmicrosoft.com/v2.0) 
    string authority = "https://login.microsoftonline.com/common/v2.0" ; 

    /// <summary> 
    /// Configure OWIN to use OpenIdConnect 
    /// </summary> 
    /// <param name="app"></param> 
    public void Configuration(IAppBuilder app) 
    { 
     app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType); 

     app.UseCookieAuthentication(new CookieAuthenticationOptions()); 
     app.UseOpenIdConnectAuthentication(

     new OpenIdConnectAuthenticationOptions 
     { 
      // Sets the ClientId, authority, RedirectUri as obtained from web.config 
      ClientId = clientId, 
      Authority = authority, 
      RedirectUri = redirectUri, 
      // PostLogoutRedirectUri is the page that users will be redirected to after sign-out. In this case, it is using the home page 
      PostLogoutRedirectUri = "https://localhost:44368/Claims/Register", 
      Scope = OpenIdConnectScopes.OpenIdProfile, 
      // ResponseType is set to request the id_token - which contains basic information about the signed-in user 
      ResponseType = OpenIdConnectResponseTypes.IdToken, 
      // ValidateIssuer set to false to allow personal and work accounts from any organization to sign in to your application 
      // To only allow users from a single organizations, set ValidateIssuer to true and 'tenant' setting in web.config to the tenant name 
      // To allow users from only a list of specific organizations, set ValidateIssuer to true and use ValidIssuers parameter 
      TokenValidationParameters = new System.IdentityModel.Tokens.TokenValidationParameters() { ValidateIssuer = false }, 

      // OpenIdConnectAuthenticationNotifications configures OWIN to send notification of failed authentications to OnAuthenticationFailed method 
      Notifications = new OpenIdConnectAuthenticationNotifications 
      { 
       AuthenticationFailed = OnAuthenticationFailed, 
       AuthorizationCodeReceived = (c) => { 
        var code = c.Code; 
        return Task.FromResult(0); 
       } 
      } 
     } 
    ); 
    } 

    /// <summary> 
    /// Handle failed authentication requests by redirecting the user to the home page with an error in the query string 
    /// </summary> 
    /// <param name="context"></param> 
    /// <returns></returns> 
    private Task OnAuthenticationFailed(AuthenticationFailedNotification<OpenIdConnectMessage, OpenIdConnectAuthenticationOptions> context) 
    { 
     context.HandleResponse(); 
     context.Response.Redirect("/?errormessage=" + context.Exception.Message); 
     return Task.FromResult(0); 
    } 
} 
}

從Azure AD's v2.0 endpoint docs：

註冊後，應用程序通過發送請求到V2.0端點Azure的AD通信：

https://login.microsoftonline.com/{tenant}/oauth2/v2.0/authorize https://login.microsoftonline.com/{tenant}/oauth2/v2.0/token

凡{tenant}可以採取一個有四種不同的值：

• common - 允許用戶使用Azure Active Directory中的個人Microsoft帳戶和工作/學校帳戶登錄到應用程序。
• organizations - 只允許用戶從Azure的Active Directory的工作/學校帳戶登錄到應用
• consumers - 只允許用戶與個人賬戶微軟（MSA）登錄到應用程序。
• 8eaef023-2b34-4da1-9baa-8bc8c9d6a490或contoso.onmicrosoft.com - 只允許具有來自特定Azure Active Directory租戶的工作/學校帳戶的用戶登錄到應用程序。可以使用Azure AD租戶的友好域名或租戶的guid標識符。

如果您想進一步降到消費者域（@ live.com VS @ outlook.com）限制你需要實現自己在應用層面看email要求。請注意，通常這種級別的過濾沒有多大意義，因爲live.com帳戶和outlook.com帳戶之間沒有功能/實用差異，他們只是有一個不同的虛榮域。
