I'm writing a script to backup some local directories on a unix machine (Ubuntu) to a samba drive. The script works fine and I've got it running at shutdown and restart using the method described at http://en.kioskea.net/faq/3348-ubuntu-executing-a-script-at-startup-and-shutdown

It works by placing the backup script into the /etc/rc6.d and /etc/rc0.d directories.

However there is a problem. After looking at the scripts logfile it seems to be run after the user is logged out. We are using LDAP authentication and when the user logs out, the system cannot backup to their samba share.

Does anyone know of anyway to run the script before the user is logged out?
