Re: Modify indexes on a delta-syncrepl consumer

Well actually I am using nearly the same configuration as explained on openldap.org: http://www.openldap.org/doc/admin24/replication.html#Delta-syncrepl

The only thing I have added is the replication of the cn=schema,cn=config so that I don't need to keep schemas in sync myself:

dn: olcDatabase={0}config,cn=config
changetype: modify
add: olcAccess
olcAccess: to dn.subtree="cn=schema,cn=config" by dn="cn=replicator,ou=ldapusers,dc=domain,dc=tld" read

dn: olcOverlay=syncprov,olcDatabase={0}config,cn=config
changetype: add
objectClass: olcOverlayConfig
objectClass: olcSyncProvConfig
olcOverlay: syncprov

So maybe the problem resides somewhere in these few additional lines. Do you see anything wrong here or anything to correct?

For instance I would like to add new indexes (olcDbIndex) on the consumer to my replicated HDB database but this fails as you can see here:

Looks like you are you also replicating cn=config.

It appears you have 3 options:

1) Do not replicate cn=config and allow individual changes at each node.

2) Replicate cn=config to all servers and modify cn=config on the provider.

3) Use multimaster replication or configure referrals and perhaups
  chaining to allow changes on each node.
