Ok, the issue here is that with winbindd running, the actual
UNIX user name is :


This should be a valid username for CUPS, as it is also a
valid username for UNIX. With winbindd not running then the
username may well be just "user" - but this doesn't look like
a Samba issue to me, it looks like an issue with CUPS mangling
valid UNIX usernames.
