Description:

I added a printer with https and authentication on a remote cups server. However when I try printing I get no password request and the job fails. I tried the same configuration on other boxes and things work smoothly, so I am afraid this is an arch linux problem.

Additional info:
* package version(s)
extra/cups 1.5.2-1

Steps to reproduce:
- Add https printer on remote server with authentication
- Try printing and get no password prompt
- Job gets held with /usr/lib/cups/backend/https failed

Dear Jelle,

you are perfectly right, sorry about that!

how's cups 1.5.3 ?
Comment by Luca Silvestrini (silvest) - Tuesday, 22 May 2012, 10:16 GMT
I can print only from firefox, where I do get a password prompt. However, from other applications such as okular I don't get a password prompt and the job gets held for authentication.

I attach the log.

Thanks a lot in advance for your help,
Luca

Please post your cupsd.conf. I guess if you configure Authentification as strictly required it should
work with any client application that basically supports it.

Do you see something on the clients command line?

My cupsd.conf is attached. Unfortunately I do not see anything on the clients command line.
Please let me know if there is any additional info I can provide.

Thanks again,
Luca

You config seem pretty default. I don't find any Authentification per job enabled. Why does your system ask for one?

May this be a setting in your printer device? What do you mean with "I added a printer with https and authentication on a remote cups server" ?

So far this seems to be no bug but a configuration issue.
Comment by Luca Silvestrini (silvest) - Thursday, 07 June 2012, 13:44 GMT
Yes, this is a setting in the printer device. By "I added a printer with https and authentication on a remote cups server" I mean the following:
- I added a printer with uri https://some.remote.server:631/printers/xxx
- In the default options of the printer, in the policy options I set "authenticated" in the Operation policy box.
As far as I understand, this should ask for authentication when submitting the job to the remote server, and indeed that is what happens on other boxes and on my box only when printing from firefox.

Please let me know if I should provide you with other configuration files.

Thanks again,
Luca

I'd move the authentification to the job policy setting in cupsd.conf not to one single printer. But both should work.

I don't know how such authetification is done in user applications. Maybe some have been compiled without openssl/gnutls support or
even without cups presence at build time. You may want to google for similar issues or ask on the cups mailing list.

I tend to close this as not a bug (of cups).

Well, even if I try to print from the command line with lpr I get no request for authentication. Isn't this a cups problem?

Thanks again,
Luca
