I have my solution, so I'm mainly just curious as to what the cause of this is and it may be slightly off topic, but this seems the most appropriate place to ask. Basically, I've been using an expect script to run `slapconfig -backupdb` to perform Open Directory backups resulting in encrypted disk images. It worked like a charm on numerous Mac OS X 10.5 Leopard Server installs, run by cron. However, after upgrading each of these servers to Snow Leopard Server, we found the disk images were not created. cron was running the script, but `diskimages-helper` would throw an exception, as seen in /var/log/system.log: Jul 23 03:00:08 servername hdiejectd[93114]: running Jul 23 03:00:11 servername diskimages-helper[93111]: -frameworkCallbackWithDictionary: threw exception calling home. Jul 23 03:00:11 servername diskimages-helper[93111]: threw exception reporting results back to framework. Jul 23 03:00:21 servername hdiejectd[93114]: quitCheck: calling exit(0) The expect script works perfectly fine when run from the shell as root. I wrote a new bash script which uses `serveradmin` (so the wrapper for `slapconfig -backupdb`) and therefore doesn't require expect, but it had the same result. However, as soon as I switched to to being run by launchd instead of cron, it works perfectly. So, what might've changed between Leopard Server and Snow Leopard Server that would cause `diskimages-helper` to throw the exception when run from cron, but _not_ when run by launchd?
