Automatically mapping shared drive in OS X 10.4

I am currently working on getting our Mac stations to play well with Active Directory. So far, I have gotten to the point where I can login into a Mac(running 10.4) using any Active Directory account. The next step is to get the users network drives to automatically map when they login. I know how to do this for each individual user(using login items), but I am trying to do this for any user that logs into the machine.

Any ideas?? THANKS!!
