[EDIT] I get confused between 'automount' and 'autofs' it appears that they are complemntary programs, you can find more info if you follow the second link.
The shares show up under /cifs. I use the following format to access the shares /cifs/hostname:share:user for example to get a listing of my home directory on crobin I would:
auto.cifs perl script
Info regarding automount and autofs
