You should get an authentication popup dialog if CUPS detects there's
a need for it. Here's how it works: 
- the authentication settings are set at CUPS-level (through cupsd.conf)
- on startup, kdeprint registers itself to CUPS to handle password
requests
- when CUPS needs a password, it triggers the registered components for
password request
- kdeprint pops up a password dialog

The info (username and password) you specify in the kdeprint settings
dialog are used as "first try". If it fails, CUPS should ask another
password
and the dialog should popup.
