Hi Brent,
By default Web Wiz Forums uses NT authentication (e.g. DOMAIN\USERNAME) and displays the username portion on posts.
The MOD that I wrote enhances this method to query Active Directory and update the name with displayName, and also get the physicalDeliveryOfficeName, title and email fields from AD. The user does not have to "log in" as the system already knows who they are.
I've included documention in the code, so it may be worth opening the two asp files within the MOD (use notepad) and view the source to see what's happening.
The instructions I wrote were designed as a step-by-step guide. The system will happily work with SQL Express - Microsoft have now release the management studio component for SQL Express, so the same instuctions should work for both.
Hope this helps, but if anything needs further explaination, please post back.
