I'm facing a similar problem. I'm testing N-way multimaster replication with OpenLDAP 2.4.13.
I'm able to successfully import data into an instance and have my two masters to sync correctly but then when I try to add a new entry in one of the two masters, I'm getting strange messages :
let's say we have m1 & m2 (m1 & m2 are on the same server): I initial import data into m1, it is successfully imported into m2 (at least it looks like it). Then I'm trying to add an entry on m2 (cn=adrien-externe.futschik@edfgdf.fr,ou=personnes,o=edfgdf,c=fr). I'm getting strange message on m1 & m2 :

Is this a bug ? Am-I doing something wrong ?
If I add the same entry to m1 and not m2 I get the following messages :

I have no idea where I found those at... I know it wasn't the (recent) admin guide. It may have been from around the 2.4.8 release, but that is long gone...

Here is the quick and dirty what I am trying to do:
ldap1 and ldap2 are supposed to be in MultiMaster. They are time synced to pool.ntp.org and each other (if they drift I would rather they sorta drift together, but pool should be keeping that in check).
Right now I am just beating them up to see how 2.4.13 performs. (So far VERY well, minus this little problem)
I have a rather small ldif (41 entries) that just wont sync (I'm starting small). Debug gives me

I am not exactly sure how it gotten to be "too old." The ldif I am importing is not the result of a slapcat or anything that would preserve the CSN or UUID attributes (not that syncrepl uses UUID). I am loading one single file with ldapadd which, in my understanding, sets up the CSN and wouldn't let me import one anyway.
Each server has no entries until I load the one, so there shouldn't be any weird stale CSNs causing this. They are "sync'ed" almost instantly after the one system is loaded - I just don't have everything.
After a sync: ldap1 - slapcat |grep dn: |wc -l = 41 ldap2 - slapcat |grep dn: |wc -l = 18
Right now I can get them in sync with a slapcat/slapadd, but when the go into production I wont be able to say for certain which one is authoritative. That is the purpose of multi-master....

Any ideas as to what I can do to stop this from happening?

Is this a bug ? Am-I doing something wrong ?
If I add the same entry to m1 and not m2 I get the following messages :

Here is the entry I'm adding :

pretty simple isn't it ? What's going wrong ?

Where did you read that those were needed anyway? If it was the admin guide then I need to fix it ;-)
Gavin.
I have no idea where I found those at... I know it wasn't the (recent) admin guide. It may have been from around the 2.4.8 release, but that is long gone...

Try dropping nopresent and reloadhint relating to ITS5669. You only need these two syncprov settings on an accesslog db.

Thanks, that did the job!
