I've been working on our development server at work to try to help streamline some process. This included upgrade Subversion and Apache to the latest versions and installing Trac (so we can better track software issues.)
In order to really simplify being able to give developers and contractors access to the appropriate areas, I wanted to try and simplify the process by configuring Apache to use Windows Authentication. This allows us to control who has access to what, just by making them members of the appropriate groups.
Since I'm new to Apache, this whole process has taken longer than what I wanted—but I certainly learned a lot in the process.
