I am running a RedHat IdM environment and am having regular problems with missed replications. I want to understand how it's supposed to work better so that I can make reasonable hypotheses to test, but I cannot seem to find any in-depth documentation for it. Every time I think I start to piece together an understanding, experimentation makes it fall apart. Can someone either point me to some documentation or help me understand how it works?
In particular, IdM implements multimaster replication, and I'm initially trying to understand how changes are replicated in that environment. What I think I understand is that changes beget CSNs, which are comprised of a timestamp and a replica ID, and some sort of comparison is made between the most recent CSNs in order to determine what changes need to be sent to the remote side. Does each replica keep a list of CSNs that have been sent to each other replica? Just the replicas that it peers with? Can I see this data? (I thought it might be in the nsds5replicationagreement entries, but the nsds50ruv values there don't seem to change.) But it feels like it doesn't keep that data, because then what would be the point of comparing the CSN values be? Anyway, these are the types of questions I'm looking to understand. Can anyone help, please?
