Noriko,

Just to let you know, after I replicated/created the exactly same OU structure on both side, the replication seems to works fine. I'm still not sure that is the expected behavior:

Yes, it is.  Winsync does _not_ sync the OU structure - you have to set that up manually so that the OU structure in AD matches the OU structure in 389.

Noriko,

Did you use the same version of 389-ds-base against AD on 2008 R2 and 2012 R2?

389-Directory/1.3.4.8 B2016.063.1654

Please share the output frpm this command line "rpm -q 389-ds-base"?

I compiled 389 manually once the package in apt repo is too old for me (I'm using ubuntu 14.04 LTS). What specific info do you need?

ds-base is 1.3.4.8

Does this error message follow some other detailed error messages?  Such as ...

YOUR_AGREEMENT_NAMEFailed to send %s operation: LDAP error (ERROR_CODE) ERROR_MESSAGE

or 

YOUR_AGREEMENT: Received error [%s] when attempting to %s entry [%s]: Please correct the attribute specified in the error message.  Refer to the Windows Active Directory docs for more information.

If not, could you enable the replication log level and share the error log with us?

After enable replication log level:

Once I do not have the same OU structure on both side (for testing purposes), I created "ou=pop-go,ou=POPS,ou=EXTERNOS,ou=RNP,dc=homolog,dc=rnp" on AD side and started to get error in another OU that I have on 389 side but not in AD.

Is that the expected behavior?

PS: In my production environment we use this strategy that what we dont want to be replicated, just not create the OU structure and works fine. I never found a better way to do that like a "exclude list".

Could you also share your Windows Sync agreement?  Do you happen to have 2 Directory Servers -- one for 2008R2 and another for 2012R2, could you provide both?

In this testing environment, I just have 2012 r2 (I upgraded all DCs to 2012). Right now, I don't have any 2008 r2 to test. 

In my production environment I have:

389-ds-base 1.3.2.19 + Windows 2008 r2

Both 2008 R2 and 2012 R2 are supported.

After configure the AD replication and Initiate a full sync, it starts to do some entries and I got the following error:

[16/May/2016:16:36:47 -0300] NSMMReplicationPlugin - windows sync - agmt="cn=AD - DF-GTI-DC01" (gti-df-dc01:636): windows_process_total_add: Cannot replay add operation.

And after that:

I found a really old ticket that seems to be related to same error:

https://fedorahosted.org/389/ticket/47589

This is a regression only affected 389-ds-base-1.3.1.x.  So, 1.3.4.x does not need the patch.

but with win2008r2 and fixed.

According to this link -> https://access.redhat.com/documentation/en-US/Red_Hat_Directory_Server/10/html/Administration_Guide/supported-ad.html

2012 R2 is supported, is that true?

Could you also share your Windows Sync agreement?  Do you happen to have 2 Directory Servers -- one for 2008R2 and another for 2012R2, could you provide both?

Any clues?
