I have two computers, one with Ubuntu 14.04 LTS and one with Ubuntu 16.04 LTS. On both computers I have configured the printer with cups to print by using my Kerberos credential in the same way and it works in 14.04 but not in 16.04.

For both 14.04 and 16.04 I have that /usr/bin/smbspool_krb5_wrapper is chmod 700.
I have "AuthInfoRequired negotiate" in /etc/cups/printers.conf.
I have made a symbolic link from /usr/lib/cups/backend/smb to /usr/bin/smbspool_krb5_wrapper.
I have set "LogLevel debug" in /etc/cups/cupsd.conf.

In 16.04 the print job just stays listed forever in "lpq" until I manually remove it with "lprm", while it goes through to the printer in 14.04.

I attach how it looks like in /var/log/cups/error_log, after setting "LogLevel debug" in /etc/cups/cupsd.conf, in 16.04 where it does not work (I have just changed my uid and gid to 1000). When I compare the log with 14.04 where it does work I see that 16.04 uses two backslashes when setting KRB5CCNAME while 14.04 does not use backslashes, maybe that is the problem?

Thanks for any ideas about what goes wrong in 16.04 or how I can track down the problem, i.e., by comparing with 14.04 where it does work!
