Working with OS X, Windows, Active Directory and other network services as much as I do, I came across a great tip when adding a leopard based machine to a AD domain today. After you bind the machine to the domain, make sure to enable the option called “Create mobile account at login”, especially if the machine is a notebook. I’m not going to say I learned this from experience, but hey you get the drift.
After binding to your domain, select “Show Advanced Settings” and select the “Services” tab. Open the Active Directory settings and enable the Create Mobile Account at Login check box and confirmation box if necessary.
