将SAML断言响应/安全上下文传播到下游服务/应用 [英] Propagate SAML Assertion Response/Security Context to downstream Services/Apps
问题描述
我们的环境中有多种服务.
We have multiple services in our environment.
在某些情况下，我们希望用户自动登录/静默登录一个或多个参与服务，而不会受到身份提供者的质询或在从一个服务首次成功登录后与身份提供者进行通信的挑战.
There are scenarios where we want the user to auto-login/silently login to one or more participating services without being challenged by the Identity Provider for credentials or communicating with the Identity Provider after the first successful login from one service.
例如，我们有一个前端UI App，我们希望使用Spring Security SAML对其进行身份验证.而且，当UI App与后端服务通信时，我们希望将安全上下文/声明响应自动传播到后续服务调用.
For Eg, we have a front-end UI App which we want to be authenticated using Spring Security SAML. And when the UI App communicates to back-end services we want the security context/assertion response to be propagated automatically to subsequent service calls.
也许，被调用的服务/应用程序可以相应地验证断言响应，并允许访问其服务/应用程序，而无需每次访问时都使所有服务/应用程序直接与身份提供商进行通信.
Perhaps, the invoked services/app can validate the Assertion Response accordingly and allow access to their services/applications without having the all the services/apps to communicate directly with Identity Provider every time they need to be accessed.
是否存在一种方法，可以将通过身份提供者成功身份验证后获得的SAML声明响应从一个应用程序/服务传播到从SAML身份验证的应用程序/服务调用的其他下游应用程序/服务.
Is there a way to propagate the SAML Assertion response obtained after successful authentication with Identity provider from one app/service to other downstream apps/services which are being invoked from the SAML authenticated app/service.
我尝试向Identity Provider注册2个应用程序，然后成功通过IdP对一个应用程序进行了身份验证，但是无法从第一个应用程序成功访问另一个应用程序.当我使用Spring的RestTemplate按下以下服务时，我收到一条错误消息.
I tried to register 2 apps with Identity Provider and then authenticated one with IdP successfully, but am not not able access the other App successfully from the first one. I get an error message when I use Spring's RestTemplate to hit the service as below.
我不确定是否所有下游应用程序/服务都应向IdP注册.
I am not sure if all downstream apps/services should be registered with IdP or not.
在成功通过Idp进行身份验证以及尝试调用另一个也由Idp保护的应用程序后，我在第一个应用程序中收到以下错误消息.
I get an error message as below in the first app after it has successfully authenticated with Idp and when it is trying to invoke another app which is also secured with Idp.

我正在使用okta作为示例应用程序的身份提供程序.
I am using okta as the Identity Provider for my sample application.
从错误中我看到它正在要求我们向身份提供者发出AuthN请求，因为它不是直接通过浏览器而是通过代码完成的.
From the error I see it is asking us to make a AuthN request to the Identity provider as it is not done directly from the browser but through code.
有人可以以正确的方式帮助我解决此问题，以便我可以成功地通过一个应用程序(SP)进行身份验证，并将安全上下文/声明响应传递给该流程中涉及的后续应用程序/服务.
Can someone help me on the right way to approach this problem, so that I can successfully authenticate with one app (SP) and pass the security context/assertion response to subsequent apps/services which are involved in that flow.
谢谢

推荐答案
一种具有SAML用户身份验证上下文传播的解决方案是使用IdP代理.
One solution to have the SAML User Authn Context propagation is by using IdP-Proxy.
Okta-IdP< --->您的IdP代理< --->您的SP-应用
Okta-IdP <---> Your IdP-Proxy <---> Your SP-Apps
IdP代理是位于IdP和SP之间的SAML到SAML网关(如上所示). IdP代理必须具有SP组件(以便它可以与Okta-IdP进行通信)，并且还必须具有IdP组件(以便可以与您的SP应用程序进行通信).
IdP-Proxy is a SAML-to-SAML gateway that sits between an IdP and an SP (as shown above). IdP-Proxy must have an SP component (so it can talk to the Okta-IdP) and it must also have an IdP component (so it can talk to the your SP-Apps).
您可以使用Okta IdP配置您的IdP代理，然后将N个SP应用程序配置到您的IdP代理，它可以直接与Okta-IdP对话以验证用户身份.然后Okta将SAML断言发送到IdP代理，IdP代理对其进行验证，生成特定于请求的SP-App的新SAML断言，并将该断言发送到请求的SP-App.
You can configure your IdP-Proxy with Okta IdP, then configure N-number of SP-apps to your IdP-Proxy and it can talk to Okta-IdP directly to authenticate user. Then Okta send SAML Assertion to IdP-Proxy, IdP-Proxy verifies it, generate a new SAML Assertion particular to the requested SP-App and send that assertion across to the requested SP-App.
