I am trying to print to a samba printer via CUPS. I have configured the printer allright, but there seems to be a problem with authentication. The error message I get is
Session setup failed: NT_STATUS_LOGON_FAILURE
The GUI also tells me:
Idle - Tree connect failed (NT_STATUS_ACCESS_DENIED)
It used to work with previous versions of CUPS (1.4.3 and 1.4.6) under Ubuntu 11.04
I am doing this on a clean install of Ubuntu 12.04, CUPS version 1.5.3. I have tried changing some rights relating to apparmor, with no success as described here: http://www.compdigitec.com/labs/2010/01/16/fixing-usrlibcupsbackendsmb-failed-error-in-ubuntu/
I have been working with Ubuntu for years - but this is the kind of problem I need help with.
