When entering the domain, the user types a login and password. When you open the browser, the user types the login and password for the proxy. When entering the corporate site, the user must again type the same username and password.
I want to make life easier for the user and authorize automatically on the site, but the site turns out about the browser should get some identification data ..
Or, once the user has logged on to the proxy, then when the http request passes through the proxy to this corporate site, the proxy adds the username of the user to trust in the headers. But in this case, the left person can also add such a title by himself.
Independently and could not understand how this is done. The solution to this issue on the Internet has not found.
