syncrepl and structuralObjectClass operational attribute

[Jehan PROCACCIA <Jehan.Procaccia@it-sudparis.eu>]

Hello
I installed  a new openldap replica 
(openldap-servers-2.4.23-20.el6.i686) , with a partial replication 
enabled by restricting certain  branches/attributes to the binddn 
account that replicate from the master.
However, on some operation (modify userPassword for example) the 
modification fails:

Mar 22 17:51:20 ldapz2 slapd[24456]: No structuralObjectClass for entry 
(uid=bde,ou=People,dc=int-evry,dc=fr)
Mar 22 17:51:20 ldapz2 slapd[24456]: entry failed schema check: no 
structuralObjectClass operational attribute
Mar 22 17:51:20 ldapz2 slapd[24456]: null_callback : error code 0x50
Mar 22 17:51:20 ldapz2 slapd[24456]: syncrepl_entry: rid=001 be_modify 
failed (80)
Mar 22 17:51:20 ldapz2 slapd[24456]: do_syncrepl: rid=001 rc 80 retrying 
(9 retries left)

what's wrong ?
could it be related to the fact that the binddn account cannot read all 
attributes from the master ?
I did checked that he can read userpassword attribute though .
is there an ACL to be set to hte replica binddn account to allow him to 
read operational attributes ?

thanks for your help.
