Hi!

A while ago, CUPS was patched to not leak authentication information to log
files and command line arguments of printer spoolers like smbspool. See [1] and
[2] for details. This break SMB printing since "smbspool" prefers argv[0] over
the DEVICE_URI environment variable.

In Ubuntu we have a dirty quickfix right before the release (see above URL)
which just swaps this preference, i. e. evaluate argv[0] only if DEVICE_URI is
not set. However, this should be done in a cleaner way. In particular, smbspool
should normally only use environment variables.

Can you please coordinate with the CUPS developers (using the bugs below) to
find a sane solution? The ubuntu bugzilla contains a patch with our quickfix, so
you can use that in the meantime.

Thanks a lot in advance for considering,

Martin
