Finally got round to implementing this for work. As a starting point I followed the instructions found here. The config looked fine, but after restarting the service, I still wasn’t getting prompted for a log in. After re-jigging the order to what you see below and restarting the apache service (we are using 2.0.59), it all worked. Maybe this will help someone else along the way.
