This bring me a new question (which I think I already get replied or found in some place but now I'm unable to find)
On a multiple replica setup (N-way Multimaster) setup, how does the server identify itself in the multiple olcSyncrepl attributes to avoid trying to replicate against itself ?
Hi Marc, the main mechanism is that syncrepl stanzas where provider matches one of our configured URIs are not activated. And since you need to have olcServerID URIs set up as well, that's usually it.
There's also some filtering based on the serverID as transmitted in the consumer's cookie but that's only a partial reduction. Regardless, even if a server started replicating from themselves you should experience no issues/endless loops if that's what you're worried about.
