Syncrep problem or bug? (openldap 2.2.11)

["Lozano, Carlos A." <clozano@andago.com>]

Hello,

I am trying to make a partial replica using syncrep. But
it is replicating (and removing) data what it shouldn't.

On the start:

The master has:

# david, usuarios, andagosoft.es
dn: cn=david,ou=usuarios,dc=andagosoft,dc=es
objectClass: top
objectClass: posixAccount
objectClass: person
cn: david
uid: david
uidNumber: 1006
gidNumber: 1006
loginShell: /bin/bash
gecos: gecos
description: description
homeDirectory: /home/david
sn: david

(config: sessionlog 100 100000)

The slave has:

# david, usuarios, andagosoft.es
dn: cn=david,ou=usuarios,dc=andagosoft,dc=es
objectClass: top
objectClass: posixAccount
objectClass: csicUsuario
uid: david
uidNumber: 1006
gidNumber: 1006
gecos: david
loginShell: /bin/bash
homeDirectory: /home/david
csicUbicacion: a01b00c00
csicDepartamento: a01b00
cn: david

(config: syncrepl rid=100
        provider=ldap://master:389
        type=refreshOnly
        interval=00:00:00:30
        searchbase="ou=usuarios,dc=andagosoft,dc=es"
        attrs="gecos,description"
        filter="(cn=david)"
        scope=sub
        schemachecking=off
        updatedn="cn=admin,dc=andagosoft,dc=es"
        bindmethod=simple
        binddn="cn=admin,dc=andagosoft,dc=es"
        credentials=secret 
)

Then after of restart the servers, the slave has:

# david, usuarios, andagosoft.es
dn: cn=david,ou=usuarios,dc=andagosoft,dc=es
uid: david
uidNumber: 1006
gidNumber: 1006
loginShell: /bin/bash
homeDirectory: /home/juan
csicUbicacion: a01b00c00
csicDepartamento: a01b00
cn: david
objectClass: top
objectClass: posixAccount
objectClass: person
gecos: gecos
description: description

The questions are: 
why has it added objectClass=person?
why has it remove objectClass=csicUsuario?
shouldn't it only replica the attrs "gecos and description"?

Thanks,
Regards,
Carlos.
