Issues adding CUPS printers to Samba with cupsaddsmb

So, once again I find myself trying to get printers from CUPS to Samba on a debian linux print/file server. I didn't have any luck with cupsaddsmb command last time, but I thought "What the heck, I know a bit more about linux now" and decided to try using it again. (The alternative is to manually add the printers to Samba, and then manually install the drivers in Samba using rpcclient or something).

I was following this somewhat updated guide. I'll just record here the error messages I got when trying to run

cupsaddsmb -v -U root -a

and the corresponding fixes.

First error messages (they typically just keep repeating if you have '-v' on, otherwise it silently fails):

Unable to copy Windows 2000 printer driver files (1)!

Server requested LANMAN password (share-level security) but 'client use lanman auth' is disabled

I guess this is a sort of bug in something, where the solution (workaround) is to add

client lanman auth = yes

to your smb.conf and restart samba

/etc/init.d/samba restart

One error message down, another one crops up. :-)

I had a feeling the line about "Server not using user level security and no password supplied" had something to do with it. On a whim, I opened up my /etc/samba/smb.conf again and changed

security = SHARE

to

security = USER

Hooray! That seemed to do the trick. Now the cupsaddsmb command runs to completion for each printer, and states that the drivers are installed for it. Of course, I'll change my security back to SHARE after I'm done installing the browsers. Guess I'll have to switch it to USER and restart samba every time I want to add another printer. Not much of a sacrifice compared to doing it the manual way -- I might switch to user based security if our company expands anyhow.
