Hi,
I have a Samba4 domain consisting of two 4.0.6 Samba servers, in two
different AD sites.
I am trying to join a new 4.0.7 Samba server as a DC.
Previously, I had had some issues caused by hardware failure of one of the
DCs; I have learnt my lesson about checking backups properly, as it took me
a surprisingly (for me) long time to recover from this (there was no FSMO
after the failure and I had to use ADSI Edit to fix this). However,
everything has been running fine since then - up till now.
Now, I try to join the new server (CentOS 6.4 clean install; Samba 4.0.7
from source), but I get the following:
(edited out to remove domain name)
[root@newdc ~]# samba-tool domain join mydomain.org DC
-UMYDOMAIN\\administrator --realm=mydomain.org
Finding a writeable DC for domain 'mydomain.org'
Found DC existing-dc.mydomain.org
Password for [MYDOMAIN\administrator]:
workgroup is MYDOMAIN
realm is mydomain.org

I think this is the same issue as in bug 9954:
https://bugzilla.samba.org/show_bug.cgi?id=9954
and in this previous post (I couldn't find a response to):
https://lists.samba.org/archive/samba-technical/2013-April/091668.html
I'm not adverse to a bit of ADSI Edit or similar - but I don't really know
where to start with this..
Any ideas?
Thanks!
Jonathan
