I tried something similar with cups 1.4.6-3.  Here's what I did:

 1. Visit <http://localhost:631/admin> with chromium.
 2. Click "Add Printer".  A dialog box appeared asking for a username and
    password.
 3. Type my (unprivileged) username and password.

The response:

	Add Printer Error

	Unable to add printer:

	Forbidden

Going back and trying to click "Add Printer" again did not give the user/password
dialog box again.  The access log from the administration tab says

	localhost - - [25/Mar/2011:00:48:00 -0500] "POST / HTTP/1.1" 401 91 CUPS-Get-Devices successful-ok
	localhost - jrn [25/Mar/2011:00:48:00 -0500] "POST / HTTP/1.1" 403 91 CUPS-Get-Devices successful-ok
	localhost - jrn [25/Mar/2011:00:47:59 -0500] "POST /admin/ HTTP/1.1" 200 1873 - -

The error log says

	E [25/Mar/2011:00:48:00 -0500] Returning HTTP Forbidden for CUPS-Get-Devices (no URI) from localhost
	E [25/Mar/2011:00:48:00 -0500] [CGI] CUPS-Get-Devices request failed with status 401: Forbidden

The configuration file says

	SystemGroup lpadmin

so presumably I ought to add myself to group lpadmin.  But in any
event, the inability to get back to step 2 (the dialog box allowing
me to choose a username and password) is puzzling.
