It is very likely 'just a bug'. We do some DNS things trying to make

This is different to what windows does, and there is a variety of
different ways DNS can be set up on windows, so clearly it isn't
interoperable right now.
Sorry about that.

If only this would have been my problem, yet the _msdcs.my.domain zone is in Windows DNS. Strange we are getting the same error.
Could not find machine account in secrets database: Failed to fetch machine account password for DOMAIN from both secrets.ldb (Could not find entry to match filter: '(&(flatname=DOMAIN)(objectclass=primaryDomain))' base: 'cn=Primary Domains': No such object: dsdb_search at ../source4/dsdb/common/util.c:4702) and from /var/lib/samba/private/secrets.tdb: NT_STATUS_CANT_ACCESS_DOMAIN_INFO

I’m not certain if the join fails because of one of these 2 errors or because of both.
I’ve looked at all the AD Partitions and the DNS AD Partitions are there and proper. I don’t know what “Zone” it is that doesn’t exist from this DNS error reported.
How did you figure out your problem was related to the _msdcs zone?
