Cups has been configured manually iirc, with a url for the printer as 
(as that was the originally the only way on FC2 I could get it to work)
As shown above, something (cups/samba ?) changes the name of a process to this URL which includes the user and password.

Version-Release number of selected component (if applicable):

How reproducible:
Didn't try

Steps to Reproduce:
I'm not sure how.

Actual Results:  Process reveals credentials through process name.

Expected Results:  Credentials hidden.

You're using the wrong URI form.  Refer to /usr/share/doc/cups-*/sam.html:


are the accepted forms.
Comment 2 Nils Olav Selåsdal 2005-08-11 08:33:33 EDT
Agreed, it seems the printers.conf has, for some odd reason

To my defence, this was created by the FC2 printer config actually, and I havnt'
touched it since upgrading.

I take it it masks out the credentials on valid URIs, and all is well.
