Re: [Samba] Recurrent DNS issues after DC loss

Ok, so what I seemed to remember was just not true.

a) I did not find any such references in any patch or release notes for Samba.

b) I managed to find the list conversation I was referring to ("userid shows 4294967295" from Dec 2015). The trouble I might run into would be due to a CentOS upgrade and the fact that system user ids then would start at 1000 and not 500 anymore.

Interesting what the mind creates of memories after a couple of years. Also interesting with which subjective certainty this can be paired.

Seems I will upgrade my DCs in the near future (and use that demote script).

I will try to find that section again. At first glance, I did not
find this information in patch notes 4.3-4.5. But I seem to remember
having read that, and I also remember a conversion with Rowland a
while ago leaving me with the impression that having different
(lower) id ranges defined will be a show-stopper for upgrading beyond
a certain point. I will try to find those emails again.

I don't remember that conversation (probably my age), but I think I
would have been referring to a classicupgrade from a PDC that had low
ID numbers. It used to be thought that using the RID as the Unix ID
number was a good idea e.g. '513' for Domain Users. This has now
proved not to be a good idea, for fairly obvious reasons.
