Thanks for writing this Bjarne. I will try it at school tomorrow. I have
a new Tjener ready to go. Then I will write up a howto on the wiki.

I would like to know the solution when you find it. When you are
successful, would you mind writing a howto for transferring users
from a skolelinux 2 tjener to a new skolelinux 3 tjener?
thanks!

Don't know if you have some machine to test on, but here is what I
have done so far. You should only use this for testing purposes.
This is not necessarily the right way, and may cause errors for what
I know, but this worked fine for me:
Backup the old ldap:
# mkdir /var/backups/ldif
# /etc/init.d/slapd stop
# /etc/init.d/nscd stop
# /usr/sbin/slapcat -l /var/backups/ldif/ldifbackup.ldif
# /etc/init.d/slapd start
# /etc/init.d/nscd start
You shold now have a ldif backup in /var/backups/ldif/ Copy this to
some removeable storage device. Then bring the ldif file to your
newly installed server. The rest is done after installing DebianEdu 3.0.
Since I had done some testing with ldap, I moved away everything in
ldap with:
# rm -rf /var/lib/ldap/*
Then got a fresh and clean ldap:
# ldap-debian-edu-install
When I tried to add my ldif file, the users would not become members
of groups already excisting, e.g. groups teachers and students.
Since, as far as I know, you can not use lwat to add several users to
a group at once, this would be quite timeconsuming. A workaround was
to restart slapd and nscd, then use lwat to remove the groups
teachers, students and machines, and then stop slapd and nscd again.
I guess you could do this from commandline as well. This step should
not be necessary, but maybe my ldif file is not corresponding to good
with my new ldap.
Then I added my ldif file using slapadd:
# slapadd -v -c -l ldifbackup.ldif -f /etc/ldap/slapd.conf
Then i did restart slapd and nscd.
# getent passwd
returns all my users
# getent group |grep teach
returns all the teachers in school correctly.
Windows (samba) machines works mostly still, but there seems to be
some issues. Sometimes they can't get in touch with ldapserver. I
have not investigated this any further.
Good luck

Sounds like a good ide for a howto wiki dokument. perhaps you could
add it to http://wiki.debian.org/DebianEdu/HowTo/MigrateLdapFrom2.0
then others that test the same procedure can help fine tune the
documentation
or if you want it as part of the official documentation package it
could be added to
http://wiki.skolelinux.no/DebianEdu/Documentation/Etch/HowTo
