[Samba] NT_STATUS_CONNECTION_REFUSED Joining Domain - Desperately need help
I am desperately in need of help. I have a Centos 7.2 server running Samba 4.6.13 as an active directory domain controller. I am trying to join a new Centos 7.4 server running Samba 4.6.13 to the domain. The domain command will not connect to the other server. I have firewalld and selinux disabled on both servers, I can ping both ways. From the new server I was able to do a kinit -U administrator and get a kerberos ticket which shows with a klist, however when I go to join the domain, I get: ERROR(ldb): uncaught exception - LDAP client internal error: NT_STATUS_CONNECTION_REFUSED File "/usr/lib64/python2.7/site-packages/samba/netcmd/__init__.py", line 176, in _run return self.run(*args, **kwargs) File "/usr/lib64/python2.7/site-packages/samba/netcmd/domain.py", line 661, in run machinepass=machinepass, use_ntvfs=use_ntvfs, dns_backend=dns_backend) File "/usr/lib64/python2.7/site-packages/samba/join.py", line 1455, in join_DC machinepass, use_ntvfs, dns_backend, promote_existing) File "/usr/lib64/python2.7/site-packages/samba/join.py", line 89, in __init__ credentials=ctx.creds, lp=ctx.lp) File "/usr/lib64/python2.7/site-packages/samba/samdb.py", line 57, in __init__ options=options) File "/usr/lib64/python2.7/site-packages/samba/__init__.py", line 114, in __init__ self.connect(url, flags, options) File "/usr/lib64/python2.7/site-packages/samba/samdb.py", line 72, in connect options=options) I have been unable to find any details in the logs on the existing server when I run this command. The join command I'm using is: samba-tool domain join redacteddomain.redacted.com DC -U"REDACTEDDOMAIN\administrator" --dns-backend=SAMBA_DLZ --option='idmap_ldb:use rfc2307 = yes' -d 10 How this problem started: I originally had two domain controllers, both of which were running Samba 4.5. I was troubleshooting a time sync issue between Windows 10 workstations and the server that appeared to come from a bug in the older Samba 4.5 version. I update the secondary domain controller to Samba 4.6.13 and that appeared to go fine, so I switched over to the primary domain controller and tried to upgrade it to 4.6.13. Something went wrong, and users were no longer able to access the domain. I switched to the backup domain controller and promoted it to primary and all was well again, so I took the original primary off-line and tried to solve the issue. After taking the old primary off-line, DNS stopped resolving for the network. Things get a bit murky at this part because my phone was runing off the hook, but I managed to wipe out the /var/lib/samba/private folder from one of the servers. Since my backups were of the old 4.5 database versions and I was unable to roll back the Samba version, I had to copy the /var/lib/samba/private folder from one server to the other, then remove the server entries for the non-working server. After that point I had to go into each machine on the network and re-join the domain because the trust relationships were no longer valid. (A domain SID changed somewhere along the way.) All but 5 machines were able to rejoin the network, and then suddenly no more could join. An additional issue is that if I do a samba_dnsupdate --verbose on the "working" server, it completes with no errors. However if I do a samba_dnsupdate --verbose --all-names I receive a ton of "TKEY Unacceptable" messages. I have worked through all the options on the wiki.samba.org "TKEY is Unacceptable" page and have not made any progress. I've got about 60 hours into troubleshooting this problem in the last 4 days and I am banging my head against a wall here. I can't seem to find anything on google about "join" returning the NT_STATUS_CONNECTION_REFUSED error, just smbclient connect attempts, and have exhausted every result returned by google on the TKEY problem. Does anyone have any ideas? Here's the extended debugging from the join command: [root at new-dc ~]#samba-tool domain join redacteddomain.redacted.com DC -U"REDACTEDDOMAIN\administrator" --dns-backend=SAMBA_INTERNAL

Whilst DCs replicate between one another, not everything is replicated and some things are specific to each DC. Do you have a backup of the original 4.5 DC that held all the FSMO roles (note, you didn't have a primary domain controller or a secondary domain controller or a backup domain controller, you just had DCs. All DCs are equal except for the FSMO roles). If you do have this backup, I would suggest you turn off all your DCS and reinstall the DC from the backup and start again. Rowland

I did find this interesting with regards to your DNS problems. getlmhostsent: lmhost entry: 127.0.0.1 localhost getlmhostsent: lmhost entry: 10.10.11.4 old-dc.redacteddomain.redacted.com I wouldn't normally expect to see lmhost entries unless explicitly created.

[Samba] NT_STATUS_CONNECTION_REFUSED Joining Domain - Desperately need help - [SOLVED]
