The print$ share is in my case a "read only" share, that can be accessed by anybody 
(guest ok = Yes). Normally any user doesn't have write access to a "read only" share, 
but with "write list" you can define which users or groups can have write access here.
Normally this is sufficient.

My Samba server is however a real domain member of a native W2k3 ADS and no 
real linux users exist on my Linux server (except the default, root and my backdoor 
root). That means that only ADS users or groups have access to my Samba shares. 
Because we have multiple country delegated admins (member of 'Domain Admins') 
they can all upload printer drivers. The reason that I use "force user = root" is that the 
uploaded printer drivers will be owned by the linux user root (uid=0 and gid=0) and 
not any Windows domain admin.

If you want to use "valid users" on your share then you have to define the users or 
groups that can have access to your share. In case of a printer driver download area 
I don't want to define users, just anybody is allowed to download them (less 

So, it just a matter of the choice you make. On the choice you make you have to use 
the "cause and effect" principle... :)
