I’m working on the company intranet at the moment which will have all sorts of different levels of access. We have been asked to come up with a system whereby the website does not have a seperate login system of any kind – a user simply logs on to their machine in the morning, and if they look at the intranet in any browser on their machine, they will only see those things that they have access to.

The intranet is using PHP on IIS.

Is their some cunning way I can get at their windows username and password via their browser, without throwing up any kind of log in?

(I would hope *not*, for y’know, security reasons, but I’m just checking.)
