Hi,
I need to set up a backup OpenLDAP cluster and I am looking for advices on the best solutions to achieve it.
The situation is: * A mirror mode cluster on one geographical site * A mirror mode cluster on another geographical site (backup site) * I would prefer not to impact configuration of main cluster * I think that full multi-master on different geographical site is not the best solution (but maybe I am totally wrong on this point)
The backup site must be in sync with the main site.
Here are my two ideas: * Configure a syncrepl client to main cluster on each node of the backup cluster. Question is: will not be conflicts as each node of the backup cluster is already synced with the other backup node? * Configure a LDAP proxy (back-ldap) to backup cluster, with syncrepl client to main cluster. But would back-ldap be able to write operational attributes to backup cluster?
I imagine that some of you already have such needs, could you share your experience?
Thanks,
Clément.
