I just fixed a bad member of my samba domain - an samba AD DC that wasn’t working. I demoted it, uninstalled Samba and reinstalled, then rejoined the domain. Everything's replicating nicely. All my users can authenticate. But my samba AD DCs are all on 4.4.16, and I want to be on 4.7. So, I set up a new server to act as my 4.7. My plan: Join it to the domain, move the FSMO role to this new server, then one-by-one replace my old DCs with new ones running Samba 4.7. I go to get the new 4.7 samba machine joined and here’s what happens: ----- samba-tool domain join mydomain.net DC -Uadministrator --realm=mydomain.net --dns-backend=BIND9_DLZ Finding a writeable DC for domain 'mydomain.net' Found DC rhea.mydomain.net Password for [mydomain\administrator]: workgroup is mydomain realm is mydomain.net Adding CN=UMBRIEL,OU=Domain Controllers,DC=mydomain,DC=net Adding CN=UMBRIEL,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=mydomain,DC=net Adding CN=NTDS Settings,CN=UMBRIEL,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=mydomain,DC=net Adding SPNs to CN=UMBRIEL,OU=Domain Controllers,DC=mydomain,DC=net Setting account password for UMBRIEL$ Enabling account Adding DNS account CN=dns-UMBRIEL,CN=Users,DC=mydomain,DC=net with dns/ SPN Setting account password for dns-UMBRIEL Calling bare provision Looking up IPv4 addresses Looking up IPv6 addresses No IPv6 address will be assigned Setting up secrets.ldb Setting up the registry Setting up the privileges database Setting up idmap db Setting up SAM db Setting up sam.ldb partitions and settings Setting up sam.ldb rootDSE Pre-loading the Samba 4 and AD schema A Kerberos configuration suitable for Samba AD has been generated at /var/lib/samba/private/krb5.conf Provision OK for domain DN DC=mydomain,DC=net Starting replication Schema-DN[CN=Schema,CN=Configuration,DC=mydomain,DC=net] objects[402/1578] linked_values[0/0] Schema-DN[CN=Schema,CN=Configuration,DC=mydomain,DC=net] objects[804/1578] linked_values[0/0] Schema-DN[CN=Schema,CN=Configuration,DC=mydomain,DC=net] objects[1206/1578] linked_values[0/0] Schema-DN[CN=Schema,CN=Configuration,DC=mydomain,DC=net] objects[1578/1578] linked_values[0/0] Analyze and apply schema objects Partition[CN=Configuration,DC=mydomain,DC=net] objects[402/1636] linked_values[0/0] Partition[CN=Configuration,DC=mydomain,DC=net] objects[804/1636] linked_values[0/0] Partition[CN=Configuration,DC=mydomain,DC=net] objects[1206/1636] linked_values[0/0] Partition[CN=Configuration,DC=mydomain,DC=net] objects[1608/1636] linked_values[0/0] Partition[CN=Configuration,DC=mydomain,DC=net] objects[1636/1636] linked_values[47/0] Unxpectedly got mismatching RDN values when checking RDN against name of CN=NTDS Settings,CN=GANYMEDE\0ADEL:9646252c-8e4d-447f-90fa-3a51355276ac,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=mydomain,DC=netFailed to convert object CN=NTDS Settings,CN=GANYMEDE\0ADEL:9646252c-8e4d-447f-90fa-3a51355276ac,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=mydomain,DC=net: WERR_GEN_FAILURE Failed to convert objects: WERR_GEN_FAILURE Join failed - cleaning up Deleted CN=UMBRIEL,OU=Domain Controllers,DC=mydomain,DC=net Deleted CN=dns-UMBRIEL,CN=Users,DC=mydomain,DC=net Deleted CN=NTDS Settings,CN=UMBRIEL,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=mydomain,DC=net Deleted CN=UMBRIEL,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=mydomain,DC=net ERROR(runtime): uncaught exception - (31, "Failed to process 'chunk' of DRS replicated objects: WERR_GEN_FAILURE") File "/usr/lib/python2.7/dist-packages/samba/netcmd/__init__.py", line 176, in _run return self.run(*args, **kwargs) File "/usr/lib/python2.7/dist-packages/samba/netcmd/domain.py", line 661, in run machinepass=machinepass, use_ntvfs=use_ntvfs, dns_backend=dns_backend) File "/usr/lib/python2.7/dist-packages/samba/join.py", line 1474, in join_DC ctx.do_join() File "/usr/lib/python2.7/dist-packages/samba/join.py", line 1377, in do_join ctx.join_replicate() File "/usr/lib/python2.7/dist-packages/samba/join.py", line 924, in join_replicate replica_flags=ctx.replica_flags) File "/usr/lib/python2.7/dist-packages/samba/drs_utils.py", line 295, in replicate schema=schema, req_level=req_level, req=req) ----- ("Ganymede" is the server I just demoted and re-promoted.)

Sadly the code checking this doesn't print the RDN value and name that it dislikes for comparison, this really wasn't expected to be seen in the field. What does dbcheck say?
