Hi cipux-devel, hi debian edu, we were recently asked to provide a method to automatically remove user directories of deleted users. To accomplish that task we wrote a python script which can be called by cron an which reads all users in the ldap database. That user list is compared with the list of directories in /skole/tjener/home0, and all directories which do not fit to a user name and which are not owned by root are removed. Use that script at your own risk - it can severly damage your system!

#
### Description:
# This script checks for all active users in the ldap directory
# and compares that list against the existing user directories of
# of a SkoleLinux installation. User directories which are not
# named after an existing user and do not belong to root are
# removed.
#
### Version
# v0.1, 2009-08-26
#
### Usage:
# The script doesn't take any arguments. Just call it and watch.
