This page describes the process for the sarge based version of Debian Edu, the etch version doesnt contain webmin.
Management of user accounts
1. How do I administer users?
With Webmin, i.e. use a web browser to go to the Server website https://tjener.intern:10000 or https://10.0.2.2:10000 and login as root with the password which you gave during the installation of the main server. Go to SYSTEM -> "Administrate Users in LDAP" and use the tools there to add users/groups and search for users to administer.
2. How do I create new users from a file?
You will find detailed screenshots of the process here (in German for now, sorry). It is important that at least the names are present in the text file (Format: CSV). If further fields are to be imported (Class, Password, Login), the fields must be separated by semi-colons. The characters strings must not be in quotation marks!
3. How do I create machine accounts?
Login as local Administrator on the Windows machine. Set the networking to use DHCP (dynamic ip address). Configure Windows to join the SMB Domain SKOLELINUX. You will be prompted for a username & password which can join the network. Give the Samba administration username and password. This will create an account on the domain for that Windows machine.
4. How do I give teachers the ability to change a pupil's password? How do they then do this?
Through Webmin (https://tjener.intern:10000).
