推荐答案

通过身份验证(前端)意味着您用于登录计算机的凭据也将用作对服务器的身份验证.

通过身份验证(后端)意味着，例如，Web服务器使用您的凭据来访问Web服务. Web服务器将设置一个线程，该线程使用您的凭据来模拟您.这意味着Web服务器上的线程的行为就好像是您自己一样.从Web服务的角度来看，Web服务器上的那个线程就是您的前端版本.

简而言之:
-您的登录凭据用于访问Web服务器.
-Web服务器上的线程使用这些凭据来模拟您，并且可以像访问您所在位置一样访问Web服务.

嗯，这是PTA的基本知识.

祝你好运！

Pass through authentication (front end) means that your credentials you used to login a computer are also used as authentication to the server.

Pass through authentication (back end) means that your credentials are used by, for example, a web server to access a web service. The web server will setup a thread that uses your credentials to impersonate you. Meaning that the thread on the web server is acting as if it was you yourself. That thread on the web sever is then the front end version of you from the point of view of the web service.

Again in short:
- You login credentials are used to access the web server.
- A thread on the web server uses those credentials to impersonate you and can access a web service as if it where you.

Well, that are the very basics of PTA.

Good luck!
