Package: cups-pdf
Version: 2.4.8-3
Severity: important
Hi there!
Note1: I set Severity: important because I cannot find any reference
about this particular problem in the CUPS-PDF documentation nor
on the net, feel free to downgrade it at most to normal.
Note2: this can be similar to bug #496317 [1], but the origins are
different, that's why I submitted a new bug.
Note3: AFAIK ncp doesn't offer a 'root_squash' option.
I setup a print server for Windows/OSX machines for the laboratory
where I work and it's working pretty well. Instead of installing one of
the free (as in beer) virtual PDF printers for Windows, I decided to
offer a different free (as in speech) solution thanks to CUPS-PDF.
A bit more about my laboratory setup: we don't use user logins, but only
one for everyone and on every computer. Since our university offers
NetWare shares (incrementally backup-ed), all of our documents are
stored on one unique NetWare volume.
My idea is simple: from their Windows/OSX machines colleagues print to
the shared CUPD-PDF printer, which saves the PDF file in one specific
folder on the NetWare volume. However, this doesn't work and there's no
useful error shown by CUPS-PDF :-(
The print server setup:
- irlab/PDF is a symlink to /mnt/Novell/PDF-Printer
- the NetWare share is mounted with ncp options
noatime,rw,exec,auto,multiple,gid=plugdev,mode=775
- /mnt/Novell, when the NetWare share is not mounted, has permissions
775 and is owned by root:plugdev
- irlab is in the plugdev group
With the setup above, even when printing from command line through lpr,
the situations is the following, with logging at level 7:
a) irlab cannot print

=====
The only error I get seems to be non fatal, which according to [2],
is not true: if this kind of error is fatal, why the '(non fatal)'
statement? And if Ghostscript exits with an error (256), why isn't
this marked as so by CUPS-PDF?
FWIW, so far I've failed to mount the NetWare share with file/mode
permission features and I've tested all the ncp options. However,
this hasn't caused any other problem until now.
FYI, irlab can write to both /mnt/Novell/PROD/PDF-Printer/ and
/var/tmp.
b) anonymous (e.g. the "Print Test Page" from http://localhost:631)
cannot print either (the CUPS-PDF log is the same)
c) root can print without any problem

I still wonder what's wrong with my setup :-(
