I have 2 set of servers and each set contains 2 servers. I have setup n-way multi master replication per set.


FirstMaster-1 ß à FirstMaster-2 – set1

SecondMaster-1 ß à SecondMaster-2 – set2


There is no replication between set1 and set2. Set 2 is inside a service network so in order to setup replication on set 2 I am trying to setup proxy on FirstMaster-1 which will point to SecondMaster-1 and FirstMaster-2 which will point to SecondMaster-2. I tried to google it but I didn’t find any body doing it for version 2.4.23.


I am able to setup a standalone proxy and configure it but I want to do it on the master servers itself.


I am trying to setup proxy for the tree Cn=Manager, dc=my-domain,dc=com on both first masters but in order to do that I have to create a ldap database with the same suffix and rootDN correct? In order to setup replication for ldap database. Ldap throws error saying “dc=my-domain,dc=com” is already defined.


FirstMaster-1 : olcDatabase={3}ldap.ldif

dn: olcDatabase={3}ldap

objectClass: olcDatabaseConfig

objectClass: olcLDAPConfig

olcDatabase: {3}ldap

olcSuffix: dc=my-domain,dc=com

olcRootDN: cn=ldap

olcSyncUseSubentry: FALSE

olcMonitoring: TRUE

structuralObjectClass: olcLDAPConfig

entryUUID: 633dcaac-1eb1-1031-884a-f7149142768b

creatorsName: cn=config

createTimestamp: 20120419212135Z

entryCSN: 20120419212135.686069Z#000000#001#000000

modifiersName: cn=config

modifyTimestamp: 20120419212135Z

olcSyncrepl: rid=000










             retry="5 5 300 5"


olcDbURI: ldap://SecondMaster-1.eng.qpass.net:389

olcDbACLBind: bindmethod=simple timeout=0 network-timeout=0 binddn="cn=Manager,dc=my-domain,dc=com" credentials="secret"


The above configuration is giving me errors when I try to reload it saying the “dc=my-domain,dc=com” is already used by the preceding database (bdb) then how do I setup the proxy on the master itself?


Your help is appreciated.
