samba-computer record at OpenLdap

[Roman Yushin <romen@infosite.ru>]

Hello.
I have an old server with openldap-server-2.0.27_3 (+ samba schema),   
samba-3.0.8,1 as PDC
All information stored at LDAP: domain-computers, domain-users

So, i have a record for computer:

dn: uid=ws01$,ou=People,o=campus,c=ru
uidNumber: 2000
gidNumber: 553
homeDirectory: /dev/null
loginShell: /bin/false
objectClass: top
objectClass: posixAccount
objectClass: sambaAccount
uid: ws01$
logonTime: 0
logoffTime: 2147483647
kickoffTime: 2147483647
pwdMustChange: 2147483647
displayName: ws01$
cn: ws01$
description: Computer
rid: 5000
primaryGroupID: 2107
acctFlags: [W          ]
creatorsName: cn=Manager,o=campus,c=ru
createTimestamp: 20060324104820Z
pwdCanChange: 1162105007
ntPassword: A49B017193432C718AA03C008C681836
pwdLastSet: 1162105007
modifiersName: cn=Manager,o=campus,c=ru
modifyTimestamp: 20061029065647Z

I am commented lines "creatorsName, createTimestamp, modifiersName, 
modifyTimestamp" and obtained ldiff-record to add it to another ldap server.

The problem is that i could not add domain-computers to new server with 
openldap-server-2.3.30!
All users were added from old ldap to new, but i have a problem with 
computers!
Here is the error

adding new entry "uid=ws01$,ou=People,o=campus,c=ru"
ldap_add: Internal (implementation specific) error (80)
       additional info: no structuralObjectClass operational attribute

If i try to add this ldiff record at old openldap, it works fine.
