Hello,

Just for information, if someone face the same issue, the problem was
due to the way we manage the DNS (manually).
As far as I understand, for the purpose of synchronization, samba
contacts the first DC using an alias (which looks like an UUID, this can
be seen in samba.log) and we were lacking this alias in our DNS.

Anyway, thank you for your reply.
