posixgroup & structuralobject errors

[jef peeraer <jef.peeraer@pandora.be>]

i am using openldap for many years now ( arround 300 users ) but 
recently i encountered some problems. i installed a new server ( 
opensuse 10.1) and tried to import an ldap database which comes from a 
suse 9.3
There seems to be a difference in schemas anyway. (opensuse 10.1 has 
openldap version  2.3.19 , 9.3 -> 2.2.23)
I've get these errors during import ->
structuralObjectClass 'posixGroup' is not STRUCTURAL
The entry on which i've got the complaints ->

dn: cn=root,ou=Group,dc=deterp,dc=be
objectClass: posixGroup
objectClass: top
cn: root
userPassword:: xxxxxxx
gidNumber: 0
structuralObjectClass: posixGroup

I did a search in the faq and on google, but didn't find very much about it.
