newbie question

[Xavier Renard <Xavier.Renard@ulg.ac.be>]

Hello, 

I'm trying to execute the example from the quick start guide but I have the 
following error:

dapadd -x -D "cn=Manager,dc=ste,dc=fapse,dc=ulg,dc=ac,dc=be" -W -f 
/home/xavier/example.ldif
Enter LDAP Password:
adding new entry "dc=ste,dc=fapse,dc=ulg,dc=ac,dc=be"
ldap_add: Object class violation
        additional info: missing required attribute

I quess what it means but, really starting from scratch (and from the docs), 
I don't really know how to resolve it (and my domain name doesn't help me 
very much as well))

Following you can find the ldif file as well  as the slap.conf

In advance, thank you for any help

Xavier
