Hello Alexander,

How did you initialize that new replica 26.
Either 'cn=System: Manage Host Keytab,cn=permissions,cn=pbac,dc=unix,dc=megafon,dc=ru' was not part of the total init data, or a DEL of that entry happened on replica 26 (before a new ADD) but the DEL was not replicated to replica12.
Would you check in replica26 access logs if that entry was deleted ?

thanks
theirry

This is correct, thank you for understanding and for helping!

Replica with id 26 was created today, this is our new server which was included in domain just a few hours ago. Looks like this dup came right after this new replica creation.

Hi,

you did send the data directly to me, maybe not wanting to share them to everyone. I'll continue discussion here, trying to be careful.

The "good" entry was created in April on replica 12 "0x0c"
createTimestamp;vucsn-5524d42b0067000c0000: 20150408070720Z

the "nsuniqueid" entry was created today on replica 26 "0x1a"
createTimestamp;vucsn-5580f3210000001a0000: 20150617040801Z

if the original entry would have existed on replica26 the new add should have been rejected, if it was not there the question is why.

Do you have any additional info on replica 26, when was it created, was it disconnected for some time ??

    No other servers in IPA domain have such duplicates.

        Hello.

        Just to remind if somebody still not familiar with our IPA
        installation J

        We currently have 18 IPA servers in domain, on 8 sites in
        different regions across the Russia.

        And now, our new problem.

        Regularly we getting a nsds5ReplConflict records on some of
        our servers, very often on servers from specific site. Usually
        it is simply a doubles and we can remove the renamed change to
        get everything back. But why do we have them at all?

        May be someone could explain, how we can detect the cause of
        this replication conflicts?

    if you are talking about having two "duplicate" entries,
    one: uid=xxxxx,<suffix>
    one: nsuniqueid=nnnnnnnn+uid=xxxxx,<suffix>

    these entries appear if the entry uid=xxxxx was added,
    simultaneously, on two servers. I think this can happen if a
    client tries to add an entry and if it doesn't get a response in
    some time retries on another server.
    to find out which client this is you need to check on which
    servers the entries were originally added and then see which
    client was doing it


    Sometime it is moderately harmful, because, for example HBAC stops
    working on specific server while doubles still present.

    Thanks in forward...
