My clients are connected to a domain and users are logged in as windows domain users.

How do I add printers while logged in as a domain user?

It asks for password for [username] on localhost. But the user is not a physical user on the localhost machine.

Adding the printer using a local admin account would not be an option because the IT support staff would then have to manually add for all the users and users shouldn't be knowing the local admin account id/pass.

Users logged on to windows terminals are able to add the printers.

What do I need to configure to allow this for users on the linux clients. I'm using Ubuntu 8.04.
