Public bug reported:
Hi,
We have our printers configured to print to a Windows print server. In
Ubuntu 14.04 and 16.04 our setup works fine but in 18.04 our setup seems
to be acting more like AuthInfoRequired username,password i.e. it
prompts for a password when printing rather than using the available
Kerberos credentials.
We are using an unaltered cupsd.conf file and are adding printers with
the following command:
lpadmin -p "printer" -D "Printer" -L "room" -v
"smb://printers.cis.strath.ac.uk/printers" -o Media=A4 -o PageSize=A4 -o
printer-error-policy=abort-job -o auth-info-required=negotiate -m "CIS
/hp-officejet_pro_476_576_series-ps.ppd"
the smb backend has been linked to /usr/lib/x86_64-linux-
gnu/samba/smbspool_krb5_wrapper (I've added this the apparmor profile as
it's blocked by default) and the permissions on this file changed to 700
(owner root) as per manpage instructions.
When using lp -d printer /tmp/test.txt I get the following response:
Password for myuid on localhost?
Typing my password gets the job accepted to the queue but it does spool
to the Windows Print Server and in the error_log file I can see
D [24/Jul/2018:10:33:00 +0100] [Job 45] SMBSPOOL_KRB5 -
AUTH_INFO_REQUIRED=negotiate
D [24/Jul/2018:10:33:00 +0100] [Job 45] SMBSPOOL_KRB5 - Started with uid=0
D [24/Jul/2018:10:33:00 +0100] [Job 45] SMBSPOOL_KRB5 - AUTH_UID is not set
As I said earlier this all works perfectly on Xenial and Trusty.
(A similar AuthInfoRequired negotiate setup also works in cups 2.2.5 on MacOS
10.13)
Any ideas how to fix this?
Thanks,
Ian.
