replication problem: no structuralObjectClass for entry

["Martin Beier" <Martin.Beier@gmx.de>]

Hi there, I've got a problem replicating
entries from my master server.


The master's version is openldap2-2.0.23-53

>From the /etc/openldap/slapd.conf

I had to create the objectClass gfiAccount, since the replica
complained when initially loading the Content of the master
using slapadd (something like object class violation person/account).
The gfiAccount in /etc/openldap/schema/gfi.schema looks like

objectclass ( 1.3.6.1.4.1.7165.1.1.1.99 NAME 'gfiAccount'
        SUP ( inetOrgPerson $ account ) STRUCTURAL)

(The OID is a fake, this will hopefully cause no errors)

Now adding an entry on the master works fine:

ldapadd -x -D 'cn=root,dc=gfi-bremen,dc=de' -W -f suff.ldif 
Enter LDAP Password: 
adding new entry
"uid=suff,ou=Systementwicklung,ou=Mitarbeiter,dc=gfi-bremen,dc=de"

The corresponding replog file looks like

cat /var/lib/ldap/slapd.replog
replica: lihb-108.vpn.gfi-bremen.de:389
time: 1092988326
dn: uid=suff,ou=Systementwicklung,ou=Mitarbeiter,dc=gfi-bremen,dc=de
changetype: add
objectClass: top
objectClass: inetOrgPerson
objectClass: qmailUser
objectClass: posixAccount
objectClass: shadowAccount
objectClass: gfiAccount

modifiersName: cn=root,dc=gfi-bremen,dc=de
modifyTimestamp: 20040820075205Z


The problem is, that the 

structuralObjectClass: gfiAccount

line is missing. When slurpd tries to add the entry,
an error occurs on the replica and the data is not being
inserted:

Aug 20 13:45:55 lihb-108 slapd[23754]: No structuralObjectClass for entry
(uid=suff,ou=Systementwicklung,ou=Mitarbeiter,dc=gfi-bremen,dc=de)

When I stop slurpd and alter the replog file manually
by inserting the structuralObjectClass line, everything
works fine after restarting slurpd.

Can anybody help please?
