Hello,
I'm a little bit worried about that mail and the fact that our setup is getting out of sync sometimes. http://www.openldap.org/lists/openldap-software/200505/msg00324.html
versions: the providers are all 2.4. The consumer is 2.4.23, some providers 2.4.21 one 2.4.11 And our setup is not stable, we get out of sync, it's a matter of days/weeks. So, is this working? Should we prefer a relay, then replicate from the relay. What is the right solution? Is there a simple way to force replication whithout deleting the database? Should I replicate to 4 databases and create refererals, then replicate the whole tree to another consumer? Thanks in advance for any advice
Dom
Our configuration on the fusion consumer:
database bdb suffix "dc=fr"
syncrepl rid=010 provider=ldap://ldapmaitre.univ-xx.fr/ type=refreshAndPersist searchbase="dc=univ-xx,dc=fr" retry="60 10 300 +" scope=sub filter="(objectClass=*)" attrs="*,modifytimestamp,modifiersName,createTimestamp,creatorsName" schemachecking=off bindmethod=simple

Running multiple different versions on your master is a great way to ensure things will not work properly. I don't know why you are surprised at having problems.

Just a thought here: you are replicating from multiple servers into a single database. Does every server have a different serverID configured? This is not the same as the syncrepl rid. If two servers are reporting the same serverID it could mess up the replication protocol because the entryCSN and contectCSN values include the ID.
I would certainly advise updating your older servers: 2.4.11 has known bugs in this area.

We have to put a serverid on each provider as global configuration, then on the consumer side, should we do something? Don't know exactly how to configure server id. Anyway, we upgraded all our servers to 2.4.23 and got the same problems, but your serverid hint makes sense.
Thanks in advance

Just trying to change my setup:
adding serverid to my provider and my internal consumer, it works without side effect but for the fusion consumer, I am no more replicating to it and I'm just trying with a single entry! And I don't know what to do to get something working. If anybody has an idea?
Thanks
