Snow Leopard Server AD Integration and Authentication

I am a newby to Snow Leopard server. We recently upgraded our Podcast Server to Snow Leopard. My question is that when I open the main web interface of the server, I see 4 choices, My Page, Wikis, Blogs, and Podcast Producer. When I try to log-in to Podcast Producer my AD credentials work. When I try to log-in to My Page, my AD credentials fail. If I setup a local account I can log-in to My Page with those credentials. I would like to get the AD integration so that any domain user can use their AD credentials to log-in. Any ideas?

 

Windows AD credentials. We use dual boot macs and can authenticate with windows AD credentials on both Mac OSX and Windows. I am not an expert on this. All know is that when I open up the web page from the Snow leopard side that I can authenticate with a lapd account for the My Page section but not with a Windows Ad account. But for the Podcast Capture icon Windows AD credentials work fine. The Snow leopard server is getting Open Directory from another OSX server.

 

Attached is what I see when I open my Snow Leopard server web page.
