MacOSX 10.3.5 need secure,authenticated printing - how?

[Dag Tore Antonsen]

Hi!

I was wondering how we can get our students using labmachines to have a 
secure, "authenticated" way of printing, using for example a password 
protected smb-server? 

Problem: 
The students have to pay for each printout. We need to make sure that it 
is this student that's doing the printout, and that it is in no way 
someone else. We need to authenticate the users before they are allowed 
to print. 

Is this possible?

I've tried LPD-printing, which works well, but is not secure (it also 
allows "fake" users), and smb-printing. But to use the 
smb-printing/smb-server you have to authenticate when setting up the 
printer. This means that your username and password is kept in 
/etc/cups/printers.conf , and we don't want that. It also means that the 
bill for all printouts on that machine goes to the person configuring 
the printers. I've tried removing the username and password, but that 
leaves us the message of authentication error.

What we want:
We need to have the user logging in on for example a MacOSX-machine to 
either be authenticated automatcially (via Active Directory or 
something), OR that it pops up a window, asking for username and 
password every time you print. We don't want to store anything about the 
user/password on the machine. Is it in someway possible to configure 
CUPS in this way?

Can anyone help?
