I read in the PHP Docs that the $REMOTE_USER variable is only available as an apache module. I'm writing an app in PHP on an IIS5 server and I need to get the user's name from their login info. It has to come right out of the NT domain, it doesn't have to be secured once I get it.
If I can't automate this step I'm going to either a, learn asp or b, hire a subcontractor to do the project or c, tell them to find someone else.
Long live PHP!
