How to configure ldap one slave - mutlimaster replication - replication

Question

I just successfully replicated Openldap using ubuntu 10.04 as master (provider), 12.04 as slave (consumer).
I'm using syncrepl method for this replication.
Below configuration for provider.ldif and consumer.ldif
### provider ###
# Add indexes to the frontend db.
dn: olcDatabase={1}hdb,cn=config
changetype: modify
add: olcDbIndex
olcDbIndex: entryCSN eq
-
add: olcDbIndex
olcDbIndex: entryUUID eq
#Load the syncprov and accesslog modules.
dn: cn=module{0},cn=config
changetype: modify
add: olcModuleLoad
olcModuleLoad: syncprov
-
add: olcModuleLoad
olcModuleLoad: accesslog
# Accesslog database definitions
dn: olcDatabase={2}hdb,cn=config
objectClass: olcDatabaseConfig
objectClass: olcHdbConfig
olcDatabase: {2}hdb
olcDbDirectory: /var/lib/ldap/accesslog
olcSuffix: cn=accesslog
olcRootDN: cn=admin,dc=teleneos,dc=org
olcDbIndex: default eq
olcDbIndex: entryCSN,objectClass,reqEnd,reqResult,reqStart
# Accesslog db syncprov.
dn: olcOverlay=syncprov,olcDatabase={2}hdb,cn=config
changetype: add
objectClass: olcOverlayConfig
objectClass: olcSyncProvConfig
olcOverlay: syncprov
olcSpNoPresent: TRUE
olcSpReloadHint: TRUE
# syncrepl Provider for primary db
dn: olcOverlay=syncprov,olcDatabase={1}hdb,cn=config
changetype: add
objectClass: olcOverlayConfig
objectClass: olcSyncProvConfig
olcOverlay: syncprov
olcSpNoPresent: TRUE
# accesslog overlay definitions for primary db
dn: olcOverlay=accesslog,olcDatabase={1}hdb,cn=config
objectClass: olcOverlayConfig
objectClass: olcAccessLogConfig
olcOverlay: accesslog
olcAccessLogDB: cn=accesslog
olcAccessLogOps: writes
olcAccessLogSuccess: TRUE
# scan the accesslog DB every day, and purge entries older than 7 days
olcAccessLogPurge: 07+00:00 01+00:00
Then below consumer.ldif
### consumer ###
#Load the syncprov module.
dn: cn=module{0},cn=config
changetype: modify
add: olcModuleLoad
olcModuleLoad: syncprov
# syncrepl specific indices
dn: olcDatabase={1}hdb,cn=config
changetype: modify
add: olcDbIndex
olcDbIndex: entryUUID eq
-
add: olcSyncRepl
olcSyncRepl: rid=0 provider=ldap://192.168.2.29 bindmethod=simple binddn="cn=admin,dc=teleneos,dc=org"
credentials=teleneos searchbase="dc=teleneos,dc=org" logbase="cn=accesslog"
logfilter="(&(objectClass=auditWriteObject)(reqResult=0))" schemachecking=on
type=refreshAndPersist retry="60 +" syncdata=accesslog
-
add: olcUpdateRef
olcUpdateRef: ldap://192.168.2.29
This is succesfully replicated, when i add value on provider, then will replicated on consumer (slave). But this is only 2 machine connected.How if i have more than 10 machine as provider(master).Should on customer.ldif add olcUpdateRef: ldap://url_ldap one by one ?
add: olcUpdateRef
olcUpdateRef: ldap://192.168.2.29
olcUpdateRef: ldap://192.168.2.30
olcUpdateRef: ldap://192.168.2.31
...
...
olcUpdateRef: ldap://192.168.2.39
Any another configuration for this case ? i think if i add one by one url of ldap master i will not effective.
Help me to solve this issue.
Thanks

It's not clear to me that this is a supported configuration or that it will work, but if so all you should need is multiple syncrepl directives in the consumer.
NB you shouldn't load the syncprov module in the consumer.
