Title: Cups wont print to smb-shared printer requiring user authentication via kerberos Status in cups package in Ubuntu: New Bug description: Setup: - Print server part of an AD domain. Print server requires authentication. - Ubuntu client with cups-server. The client is part of the AD domain. The client does not share printers (and never will). - User authenticated by AD within the AD domain. - Now user wants to print. Printer is set up: <DefaultPrinter KONICA-MINOLTA-C364Series-OpenOffice-PPD> UUID urn:uuid:85b0f3b3-67a2-3385-7fd2-57ac93c0f837 AuthInfoRequired none Info KONICA MINOLTA C364e Location E017 MakeModel KONICA MINOLTA C364SeriesPS(P) DeviceURI smb://<server>/drucker-muc PortMonitor tbcp State Idle StateTime 1576145797 ConfigTime 1576146371 Type 8401100 Accepting Yes Shared No JobSheets none none QuotaPeriod 0 PageLimit 0 KLimit 0 OpPolicy default ErrorPolicy retry-job Option print-quality 3 </DefaultPrinter> Since AuthInfoRequired is set to "none" cups thinks everyone can print and no authentication would be necessary. That's not true: the printer requires authentication. Maybe a bug. This print server requires any user to be authenticated and have a kerberos ticket. This is true. The user has a kerberos ticket and this user is allowed to print. The users kerberos ticket cache is available in memory and in /tmp/krb5_<uid>.keytab. CUPS does not seem to take it into account. May be a bug too. Changing "AuthInfoRequired" from "none" to "username,password" allows cups to print. But this has to be done editing /etc/cups/printers.conf. The web printer configuration just does not allow to set anything else than "none". This is a bug. Documentation misses what "AuthInfoRequired" has to be set for if kerberos authentication will be used. This is a bug too!
