Re: [Samba] Samba4 on Ubuntu 18.04

I installed two samba ad in replication. One fileserver (domain member) and printserver (domain member). I built a CTDB cluster with it. All are running on Ubuntu 18.04 LTS!

On the AD Server i got a problem with the internal DNS from samba because systemd-resolver thought it is the DNS boss now. I disabled systemd-resolve (systemctl disable systemd-resolved.service) and mange the resolve.conf manually.

Some tips before you install samba:

- If not needed uninstall "cloud init" (some trouble with setting hostname and /etc/hosts file):

# https://makandracards.com/operations/42688-how-to-remove-cloud-init-from-ubuntu

- If youre using ntp, disable systemd's timesyncd service (ntp service will now start after reboot)

# timedatectl set-ntp off

Please notice, in Ubuntu 18.04 stable not in BETA version, now a "swap.img" is mounted in "/" . No swap partition anymore!

In my opinion samba is ready for Ubuntu 18.04.


PS: All server were compiled from source, except the ctbd cluster, i used the repository (samba 4.7.6)

Yes, doing an active directory controller [ADC] not just a workgroup-share.
[Though, not "joining" a DC already in existance, but creating a new AD setup.]

RPvs> If so, then yes and it was hell
What exactly was hellish about it?
Is it your opinion I should use something else, compile from source, or what?
Did you get it to work satisfactorily eventually?

[I know you're a long-time list contributor, so I'm very interested in your thoughts.]

What do you need, yes i have compiled a whole samba ad dc structur with 18.04.
I have compiled Samba4 on Ubuntu from source before, but I'd really like to avoid doing that. It seems like a reasonable trade-off to sacrifice some lack of features [using an older version] for having Ubuntu maintain security patches etc.

On that note, I'm not totally wed to Ubuntu/Debian. Is there some LTS [long-term-support] distro that's dramatically better?


Its not 100% ubuntu, but these should work also on ubuntu. https://github.com/thctlo/samba4/tree/master/howtos
Thanks. I'll look at that. I'm not sure how much help it's going to be, as there are some, it appears, significant differences between Ubuntu 16.04 and 18.04. Thus, a how-to that isn't specific to 18.04 may not be that useful, as it will not have the detail needed to avoid the pitfalls of 18.04.

And while I can probably work through all the new oddities, I was hoping that someone else would have already done so and would be willing to share.

Thanks all for the initial tips.
