Mirror replication with multi databases - openldap-technical

31 Aug 2009

      Hello,
I have to deploy an OpenLDAP in mirror mode and my OpenLDAP have 10 database.
OpenLDAP is in 2.4.17 version and is deploy on Debian Lenny with Berkeley DB 4.6.
I would like to know if my config file is correct. Indeed, when i start my OpenLDAP and if i add some entries, these entries are not replicated on the second OpenLDAP.
This is my config file for the first OpenLDAP :
-----------------------------------------------------------------------

The second file is the same, but serverID is 2 and i invert the provider for the replication.

Is this config is correct or i have to change something in order to have mirror sync to work ? Thank you for your help.
