Comment 58 for bug 283811

Seems like I can print exactly one times after 'lpadmin -p GDI-Printer -o auth-info-required=none'.
Then for the next job the error-message is "Can't promt for autorization."

The first printing-job is printed normally, produces the following in /var/log/kern.log:
Apr 29 09:31:31 simon-laptop kernel: [ 7597.702015] type=1503 audit(1240990291.780:14): operation="inode_permission" requested_mask="::rw" denied_mask="::rw" fsuid=7 name="/dev/tty" pid=15021 profile="/usr/sbin/cupsd"

And changes the line in printers.conf back to:
AuthInfoRequired username,password

The second job does not add any line to /var/log/kern.log and does not re-write printers.conf and does not print.
