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!
