But what happens when one of the servers is down, does slapo-chain store the
values ?
chain + sync cant handle any request if master is down.
I made some modifications before so that a client will change into master and other clients will connect to it in case master is down, but it is only academic.
the architecture "HA + LB cluster" has been rised long before, but it seems openldap team doesnt implement it gracefully yet :-(
