Hi All,

I just successfully replicated Openldap using ubuntu 10.04 as master server (provider), 12.04 as slave server (consumer).

I'm using syncrepl method for this replication.

Below configuration for provider.ldif and customer.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://139.193.195.170 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://139.193.195.170

Now when i add any value on ldap provider, They will replicated on consumer (ldap slave server).

But on my mechanism, i will have many ldap master machine on internet which will have to replicated to one ldap slave server.I will created centralized system.
Moreover every ldap server is using dynamic Ip address which should change automatically.

So not possible for me if i must add line olcUpdateRef: ldap://ip_provider for every ldap provider on ldap configuration.

Is there configuration on ldap provider to pointing where ldap slave is ? So that, to replicate to slave server on my provider server (ldap master) , i just need pointing ip of slave ldap server is.

Help me to solve this issue.

Thanks
