Hey I'm trying to install openldap on Ubuntu 10.04 but I'm getting this annoying error which I can't figure a way around it

adding new entry “cn=module{0},cn=config”
ldap_add: Naming violation (64)

this happens when I try to configure slapd.d

This is the tutorial that I'm following, starting from 'cat << EOF > $tmpdir/database.ldif'
http://albanianwizard.org/ubuntu-10-...albanianwizard

this is what I'm entering:

cat << EOF > $tmpdir/database.ldif

I have tried other tutorials before this one but all of them resulted the same problem and couldn't find anything on the internet specific to the error I'm presented.

Please help me on this one
