从代码配置Windows Identity Foundation

我正在尝试使用“无配置WIF”,我希望接受由Windows Azure的AppFabric STS生成的SAML2令牌。

我正在做的是解析检查令牌信息的当前请求,如下所示:

        if (Request.Form.Get(WSFederationConstants.Parameters.Result) != null)
        {
            SignInResponseMessage message = 
                WSFederationMessage.CreateFromFormPost(System.Web.HttpContext.Current.Request) as SignInResponseMessage;

            var securityTokenHandlers = SecurityTokenHandlerCollection.CreateDefaultSecurityTokenHandlerCollection();                    

            XmlTextReader xmlReader = new XmlTextReader(
                new StringReader(message.Result));

            SecurityToken token = securityTokenHandlers.ReadToken(xmlReader);

            if (token != null)
            {
                ClaimsIdentityCollection claims = securityTokenHandlers.ValidateToken(token);
                IPrincipal principal = new ClaimsPrincipal(claims);
            }
        }

上面的代码使用SecurityTokenHandlerCollection.CreateDefaultSecurityTokenHandlerCollection();用于验证和处理SAML令牌的集合。但是:这不起作用,因为很明显应用程序没有正确配置。我如何在securityTokenHandlers集合中指定XML programmaticaly的后续配置?

  <microsoft.identityModel>
<service>
  <audienceUris>
    <add value="http://www.someapp.net/" />
  </audienceUris>
  <federatedAuthentication>
    <wsFederation passiveRedirectEnabled="true" issuer="https://rd-test.accesscontrol.appfabriclabs.com/v2/wsfederation" realm="http://www.thisapp.net" requireHttps="false" />
    <cookieHandler requireSsl="false" />
  </federatedAuthentication>
  <applicationService>
    <claimTypeRequired>
      <claimType type="http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name" optional="true" />
      <claimType type="http://schemas.microsoft.com/ws/2008/06/identity/claims/role" optional="true" />
    </claimTypeRequired>
  </applicationService>
  <issuerNameRegistry type="Microsoft.IdentityModel.Tokens.ConfigurationBasedIssuerNameRegistry, Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
    <trustedIssuers>
      <add thumbprint="XYZ123" name="https://somenamespace.accesscontrol.appfabriclabs.com/" />
    </trustedIssuers>
  </issuerNameRegistry>
</service>

我正在努力解决这个问题,并在WIF 3.5 / 4.0中找到了一个可行的解决方案。由于maartenba的链接似乎已经死了,我想在这里发布我的解决方案。

我们的要求是:

  • 在代码中完全配置(因为我们随应用程序提供默认的web.config)
  • 允许的最大.Net版本4.0(因此我使用的是WIF 3.5 / 4.0)

我以前用过的解决方案:

  • Daniel Wu提供的有关动态WIF配置的信息 here
  • This method David Ebbo解释说,在运行时注册HTTP模块。一世 还尝试了更优雅的方法explained by Rick Strahl, 但不幸的是,这对我来说并没有成功。
  

编辑2016/09/02:而不是添加单独的“预应用程序启动   代码“类在David Ebbo的例子中,与WIF相关的HTTP模块   也可以在静态构造函数中注册   `HttpApplication'类。我在某种程度上修改了代码   清洁解决方案。

我的解决方案在web.config中需要 nothing 。大部分代码都在global.asax.cs中。配置在此示例中是硬编码的:

using System;
using System.IdentityModel.Selectors;
using System.Security.Cryptography.X509Certificates;
using System.Web;
using Microsoft.IdentityModel.Tokens;
using Microsoft.IdentityModel.Web;

namespace TestADFS
{
  public class SessionAuthenticationModule : Microsoft.IdentityModel.Web.SessionAuthenticationModule
  {
    protected override void InitializePropertiesFromConfiguration(string serviceName)
    {
    }
  }
  public class WSFederationAuthenticationModule : Microsoft.IdentityModel.Web.WSFederationAuthenticationModule
  {
    protected override void InitializePropertiesFromConfiguration(string serviceName)
    {
      ServiceConfiguration = FederatedAuthentication.ServiceConfiguration;
      PassiveRedirectEnabled = true;
      RequireHttps = true;
      Issuer = "https://nl-joinadfstest.joinadfstest.local/adfs/ls/";
      Realm = "https://67px95j.decos.com/testadfs";
    }
  }

  public class Global : HttpApplication
  {
    static Global()
    {
      Microsoft.Web.Infrastructure.DynamicModuleHelper.DynamicModuleUtility.RegisterModule(typeof(SessionAuthenticationModule));
      Microsoft.Web.Infrastructure.DynamicModuleHelper.DynamicModuleUtility.RegisterModule(typeof(WSFederationAuthenticationModule));
    }

    protected void Application_Start(object sender, EventArgs e)
    {
      FederatedAuthentication.ServiceConfigurationCreated += FederatedAuthentication_ServiceConfigurationCreated;
    }

    internal void FederatedAuthentication_ServiceConfigurationCreated(object sender, Microsoft.IdentityModel.Web.Configuration.ServiceConfigurationCreatedEventArgs e)
    {
      X509Store store = new X509Store(StoreName.My, StoreLocation.LocalMachine);
      store.Open(OpenFlags.ReadOnly);
      X509Certificate2Collection coll = store.Certificates.Find(X509FindType.FindByThumbprint, "245537E9BB2C086D3C880982FA86267FBD66B9A3", false);
      if (coll.Count > 0)
        e.ServiceConfiguration.ServiceCertificate = coll[0];
      store.Close();
      AudienceRestriction ar = new AudienceRestriction(AudienceUriMode.Always);
      ar.AllowedAudienceUris.Add(new Uri("https://67px95j.decos.com/testadfs"));
      e.ServiceConfiguration.AudienceRestriction = ar;
      ConfigurationBasedIssuerNameRegistry inr = new ConfigurationBasedIssuerNameRegistry();
      inr.AddTrustedIssuer("6C9B96D90257B65B6F181C2478D869473DC359EA", "http://NL-JOINADFSTEST.joinadfstest.local/adfs/services/trust");
      e.ServiceConfiguration.IssuerNameRegistry = inr;
      e.ServiceConfiguration.CertificateValidationMode = System.ServiceModel.Security.X509CertificateValidationMode.None;
    }

    protected void Application_AuthenticateRequest(object sender, EventArgs e)
    {
      FederatedAuthentication.WSFederationAuthenticationModule.ServiceConfiguration = FederatedAuthentication.ServiceConfiguration;
    }
  }
}

用法

我的应用程序是asp.net WebForms,以经典管道模式运行,支持表单身份验证以及ADFS登录。因此,身份验证在所有.aspx页面共享的公共基类中处理:

    protected override void OnInit(EventArgs e)
    {
      if (NeedsAuthentication && !User.Identity.IsAuthenticated)
      {
        SignInRequestMessage sirm = new SignInRequestMessage(
          new Uri("https://nl-joinadfstest.joinadfstest.local/adfs/ls/"),
          ApplicationRootUrl)
        {
          Context = ApplicationRootUrl,
          HomeRealm = ApplicationRootUrl
        };
        Response.Redirect(sirm.WriteQueryString());
      }
      base.OnInit(e);
    }

在此代码中,ApplicationRootUrl是以“/”结尾的应用程序路径(“/”在经典管道模式中很重要。)

由于在混合模式下注销的稳定实现并不那么容易,我也希望为此显示代码。从技术上讲,它可以工作,但我仍然有一个问题,即在注销ADFS帐户后,IE会立即再次登录:

      if (User.Identity.IsAuthenticated)
      {
        if (User.Identity.AuthenticationType == "Forms")
        {
          FormsAuthentication.SignOut();
          Session.Clear();
          Session.Abandon();
          ResetCookie(FormsAuthentication.FormsCookieName);
          ResetCookie("ASP.NET_SessionId");
          Response.Redirect(ApplicationRootUrl + "Default.aspx");
          HttpContext.Current.ApplicationInstance.CompleteRequest();
        }
        else
        {
          FederatedAuthentication.SessionAuthenticationModule.SignOut();
          FederatedAuthentication.SessionAuthenticationModule.DeleteSessionTokenCookie();
          Uri uri = new Uri(ApplicationRootUrl + "Default.aspx");
          WSFederationAuthenticationModule.FederatedSignOut(
            new Uri("https://nl-joinadfstest.joinadfstest.local/adfs/ls/"),
            uri); // 1st url is single logout service binding from adfs metadata
        }
      }

ResetCookie是一个帮助函数,用于清除响应cookie并在过去设置其到期时间)

答案 1 :(得分:0)

只是一个想法,不知道这是否有效:是不是有办法获得实际的XML(在你的情况下是空的)并在运行时通过Microsoft.IdentityModel.Configuration中的类修改它?

或者,您可以在the RedirectingToIdentityProvider event中通过修改SignInRequestMessage

在发送登录请求时修改XML中的一些内容。
