Yes, what I'm saying is not that without the guid's in /etc/hosts
replication will give errors. (we have had successful replication here
What I'm saying is, that there were some remaining WERR_BADFILE repl
errors after adding a new dc. After waiting hours, restarting samba
several times these did not go away.
Then I read the post I mentioned, and added the GUID's to /etc/hosts,
and immediately my WERR_BADFILE errors disappeared.
I no expert, and again: we've always had successful replication here as
well, without the entries in /etc/hosts. But these errors remained, and
disappeared immediately after editing /etc/hosts.
Plus there have been some more similar reports on this list, I'd say:
where there is smoke, there is a fire.
Some 'evidence' from the list archives, three different threads over the
last year, similar problem, all sharing the same solution:
Again: not saying that it will never work without the entries in
