Those pesky local home folders…

Okay, I think I have half of the battle won -- I can now authenticate OS X against AD. The issue I have NOW is that a local home folder isn't created on login. So the question: what can I do to make a local home folder be created with each new login? For example, if I'm juser, and I've never logged into that Mac before, how do I get a "juser" folder in /Users after I login? While we're at it... is there any way to speed up authentication to AD? It takes about 30 seconds to authenticate -- is that normal? Thanks! Sapridyne
