I recently went through a system upgrade, which resulted in an upgrade
of Samba to 3.0.28a. This is for a home network, so it isn't heavily
taxed (only by family members), but I do use the environment as a
sandbox of sorts for stuff that I plan to roll in to production in the
office.
I had some funky issues with authentication to start with after the
upgrade, so I went through the (somewhat) painful steps to set up
ldapsam. I managed to get all of the users set up within LDAP, and all
of the machine accounts configured within LDAP, and logging in and out
of the domain with roaming profiles (using samba to create the machine
accounts and user accounts turned out to be the right way to do it
rather than to hand modify the LDAP accounts).
The only remaining issue is with regard to printing: When a Windows user
connects to the printer (hppsc2510) and sends a test page, they get an
error stating that the job failed to print (unable to create print
job). In the log.<system name> file, I can see:

Unfortunately, it doesn't actually place anything in
/var/log/samba/cores/smbd. At least, it hasn't in the past couple of days.
I turned up the debugging to "9" and went through the same test of
printing a test page, and I got:

At this point, I'm truly unsure of what is failing. I've made sure that
/var/spool/samba exists and is world writeable. I tried moving it out
of the way and testing, and samba gave an appropriate error in the log
file. I tried shutting down CUPS and doing the same test, and samba
gave an appropriate error then, too.
I can print via the command line on the samba server (a Fedora 8 box) as
the same user who is logged in on the windows box...
Any ideas?
