The dialog cannot know which kind of password actually is required by the cupsd. There is not only one way to do CUPS authentication. The default is so called "basic" authentication using system user names from /etc/passwd and system passwords from /etc/shadow. But there is alternatively the so called "digest" authentication which uses completely seperated and arbitrary CUPS user names and CUPS passwords which are set up via "lppasswd". As fas as I know a user application program cannot ask the cupsd which kind of authentication is required for a particular request and therefore the dialog cannot show a hint to the user which kind of user name and password it likes to get. > In my case it does not with > the user's password so it might be useful to give a hint > how to set-up the CUPS-password for a user. There is even a more general problem with the CUPS authentication in hp-toolbox: The hp-toolbox authentication dialog prompts only for a password but not for a user name. But it should prompt for both user name and password preferably with the user name input field preset to the curretly logged in user. When a IPP request is sent to the cupsd which requires whatever kind of authentication, then it depends on which user name is used during this one particular CUPS authentication. The crucial point is that this can be a totally different user name than the user who is currently logged in. For example I can be logged in as normal user "jsmeix" and run: ------------------------------------------------------------------ [EMAIL PROTECTED]:~> /usr/sbin/cupsenable -U root -h localhost queue Password for root on localhost? ... ------------------------------------------------------------------ If I would try to use hp-toolbox to enable the queue, hp-toolbox would not let me choose to do it because it thinks I don't know the root password on my host (and only root is allowed to enable queues on my host). Any printing admin tool should take into account that the actual IPP request can be done under a totally different user name and password compared to the user who is logged in and who runs the admin tool process, Kind Regards Johannes Meixner -- SUSE LINUX Products GmbH, Maxfeldstrasse 5, 90409 Nuernberg, Germany AG Nuernberg, HRB 16746, GF: Markus Rex ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
