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 checking sAMAccountName Adding CN=NEWDC,OU=Domain Controllers,DC=mydomain,DC=org Join failed - cleaning up checking sAMAccountName ERROR(ldb): uncaught exception - LDAP error 53 LDAP_UNWILLING_TO_PERFORM - <00002035: ../source4/dsdb/samdb/ldb_modules/ridalloc.c:517: No RID Set DN - Failed to add RID Set CN=RID Set,CN=EXISTING-DC,OU=Domain Controllers,DC=mydomain,DC=org - objectclass: object class 'rIDSet' is system-only, rejecting creation of 'CN=RID Set,CN=EXISTING-DC,OU=Domain Controllers,DC=mydomain,DC=org'!> <> File "/usr/local/samba/lib64/python2.6/site-packages/samba/netcmd/__init__.py", line 175, in _run return self.run(*args, **kwargs) File "/usr/local/samba/lib64/python2.6/site-packages/samba/netcmd/domain.py", line 552, in run machinepass=machinepass, use_ntvfs=use_ntvfs, dns_backend=dns_backend) File "/usr/local/samba/lib64/python2.6/site-packages/samba/join.py", line 1104, in join_DC ctx.do_join() File "/usr/local/samba/lib64/python2.6/site-packages/samba/join.py", line 1007, in do_join ctx.join_add_objects() File "/usr/local/samba/lib64/python2.6/site-packages/samba/join.py", line 499, in join_add_objects ctx.samdb.add(rec) 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!
