Thanks for giving it a try and reporting back.

Thanks, fixed in SVN now. I guess all the tests I've ran were from the
source directory.

That is weird. I cannot reproduce that (though using an i386 sid test
environment here). You could try removing /var/run/nslcd/cache.sqlite*
(and perhaps lock files there) and restarting pynslcd. It should
recreate the database if it is missing. Still weird that sqlite3
command-line found the table but pynslcd didn't.

Thanks,
