Ok I guess I am not being very clear....
Ok I want to be able to authenticate a user only based on the fact that he is logged in to the local machine. If he is allowed onto the machine then I trust him...,. I know I know this is not the most secure thing but I have been challenged by some ASP guys at work.
With ASP you can certainly do this and I am hoping there is a way with php.
I.E.
I am logged into my machine as jared.skinner
I want the website to know that I am logged in as jared.skinner and then because I am already logged in and authenticated by the system the website should trust that. then take the user I am logged into the system as and compare that against a list of authorized usernames...
I know I know lots of flaws. But that is what they want....
