Thanks Shilen for the info.
I think the problem is that the entry is created before the
initialization of the consumer completes.
The created entry 'shilen3' is part of the data set send during the
initialization. So it exists on the consumer.
Now replicatoin uses a RUV to know what needs to be send to a consumer.
The RUV of the consumer does not know this entry. So the supplier is
trying to send it.
Of course the entry already exists and the update fails.
It is looking like a bug but I do not know how to fix it.
I will try to reproduce
regards

Once the init is done, the following is repeated on the consumer (when
logging is turned up). Note that the ADD was done while the init was
happening and after the init is done, the entry does exist on the
consumer but, from what I can tell, the supplier wants to still send
it to the consumer and the consumer is rejecting it.
Also, the other issue that I'm noticing is that a couple of my
consumers seem to be crashing (about once a day). Right now, they are
not getting any traffic at all other than updates from replication.
I'm debugging that at the moment and will report what I find.

Subject: Re: [389-users] Replication error after initializing consumer
Hello,
This logs are coming from the supplier. It confirms what you
said. The supplier retrieves a starting point for sending
updates (53f5e4b5000000050000) then sends the next update
53f5e647000000050000
(uid=shilen3,ou=people,ou=test,dc=duke,dc=edu). For some
reason the consumerhost:636 is unwilling to apply the update
(is the backend readonly ?).
Have you got the error logs from consumerhost (with
replication logging enabled) ?.
thanks
theirry

Hi Mark,
So with this issue, I'm not adding a password at all to the
entry. See the LDIF in (2) below.
No, I was referring to your first email, not this issue.
Sorry I should of responded separately.
I'll open a ticket.
For what issue? For the initialization issue I want you to
grab the logging first. For the first issue(userpassword not
being replicated), if you can reproduce it when only adding
already hashed passwords, then please file a ticket with a
reproducible testcase.
I hope that clears things up.

Shilen,
A few things, you should not be adding a prehashed
password (e.g. {SSHA}DMK4S6PK6+rKSLNOL1Hl01mVJmgGi5jH) -
but that should not break replication. Can you confirm
that only prehashed passwords are causing the issue? If
so, please files a ticket with a reproducible testcase:
https://fedorahosted.org/389/newticket
As for this replication issue, enabling replication
logging might provide more information:
https://access.redhat.com/documentation/en-US/Red_Hat_Directory_Server/9.0/html/Configuration_Command_and_File_Reference/error-logs.html#error-logs-levels
Then post the logging output back on this list. You
should also undo this logging level once you're done -
as this logging level can impact performance.
Thanks,
Mark

[19/Aug/2014:17:48:55 +0100] NSMMReplicationPlugin -
Finished total update of replica
"agmt="cn=test5toSing1" (consumerhost:636)". Sent 270
entries.
At this point, the entry does exist on the consumer.
Presumably it was added as part of the init.
4. However, the master still wants to send the ADD to
the consumer. On the consumer, I have the following
repeated every few seconds:
[19/Aug/2014:17:48:54 +0100] conn=2002 op=56 ADD
dn="uid=shilen3,ou=people,ou=test,dc=duke,dc=edu"
[19/Aug/2014:17:48:54 +0100] conn=2002 op=56 RESULT
err=53 tag=105 nentries=0 etime=0 csn=53f37f89000000050000
And on the master, I have this:
[19/Aug/2014:17:48:58 +0100] NSMMReplicationPlugin -
agmt="cn=test5toSing1" (consumerhost:636): Consumer

A cl-dump shows the following:

If anyone has any thoughts on this one, that would be
appreciated.
Thanks!
