I'm trying to setup samba + winbind to allow uploading and downloading
of printer drivers from a windows client.  Otherwise attaching to the 
printers and installing the drivers manually work fine.

I've followed the instructions from the samba howto collection but
still can't get it to work.

I've defined the print$ share, created the appropriate printer subdirectories
on the samba box, set the printer admin list and write list appropriately.
