"invalid structural object class chain"

[Karsten Kankowski <Karsten.Kankowski@airbus.com>]

Dear wise guys!

Sorry for a "newby" question:
I would like to load following LDIF:

dn: cn=Zaphod Beblebrox,
ou=people,cu=user,cu=a-d,cu=natco,dc=cax,dc=airbus,dc=com
cn: Zaphod Beblebrox
objectClass:Top
objectClass: Person
objectClass: organizationalPerson
objectClass: inetOrgPerson
objectClass: account
objectClass: posixAccount
gidNumber: 42
homeDirectory: /home/ZZ-Plural-Z-Alpha
userid:zaphod

I get back:
ldapadd: Object class violation (65)
        additional info: invalid structural object class chain 
(inetOrgPerson/account)

I searched before I wrote this mal the Web/ the Forum / the FAQ / the 
admin-Guide :-) I found at the admin guide chapter C1.13 an description about 
this issue. 
BUT: I´m sorry! I don´t  understand this real hard to read english.

All what I hopfully know is, that a subsequent class of a Structural can be 
one or more auxiliary OR an other Structural. I assume that 
Top->Person->organizationalPerson->inetOrgperson "looks" like one structural 
class in case that they inherit via the SUP keyword ( called superclass ?? )
For that I do not understand why the account object class can´t be "connect" 
to that superclass. 
What´s wrong here and how do can I use the account as  subsequent class of 
inetOrgPerson. The "connect" of posixAccount to account should be also 
possible.

Thanks a lot for your help in advance,

Karsten
