Configuring Proxy on Master Master replication set issues - openldap version 2.4.23 - openldap-technical

19 Apr 2012


      Hi,
I have 2 set of servers and each set contains 2 servers. I have setup n-way multi master replication per set.
FirstMaster-1 <-- --> FirstMaster-2 - set1
SecondMaster-1 <-- --> 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

             provider=ldap://FirstMaster-1:389
             binddn="cn=Manager,dc=my-domain,dc=com"
             bindmethod=simple
             credentials="secret"
             searchbase="dc=my-domain,dc=com"
             filter="(objectClass=*)"
             scope=sub
             schemachecking=off
             type=refreshAndPersist
             retry="5 5 300 5"
             timeout=1
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.
Thanks.
Bhargav.
