Re: Error 53 applying syncrepl LDIF

Hello all,

In a syncrepl setup, I understand that the syncrepl specification is
defined on the consumer server. I understand this to mean that I should
apply my LDIF (that adds the olcSyncrepl attribute to my config and hdb
backends) on the consumer server. However, ldapadd was only successful in
configuring my config backend for syncrepl, which is defined first in the
LDIF, and failed with LDAP error 53 when attempting to add the
olcSyncrepl attribute to my hdb backend; additional error info: "shadow
context; no update referral."

Is this because the olcSyncrepl attribute added to my config backend
already established my consumer server as a replica and hence subsequent
writes to the consumer server will not be accepted?

Ideally, I wanted to add the syncrepl configuration in my slapd.conf and
then convert it to cn=config; however, this doesn't appear to work with
2.4.21 because the slaptest added a uri="" to the olcSyncrepl attribute
that running slapd complained of an invalid URL for olcSyncrepl. This is
not an issue in 2.4.20.

Anyway, what's the right way for me to configure syncrepl on my 2.4.21
consumer server for both the config and hdb backends?

It works for me with 2.4.21:

dn: olcDatabase={2}hdb,cn=config
changetype: modify
add: olcSyncrepl
olcSyncrepl: rid=100 provider=${ldap_master_url} bindmethod=si
mple timeout=0 network-timeout=0 binddn=uid=zmreplica,cn=admins,cn=zimbra c
redentials=${ldap_replication_password} starttls=critical filter="(objectclass=*)" searchbase="" logfilter="(&(objectClass=auditWriteObject)(reqResult=0))" logbase=cn=access log scope=sub schemachecking=off type=refreshAndPersist retry="60 +" syncdat
a=accesslog tls_cacertdir=/opt/zimbra/conf/ca

is the LDIF I use to ldapmodify my entry.
