[Samba] ipv6 with Samba-AD-DC?

[Joachim Lindenberg]

Hi Rowland,
No, I don´t have so many devices yet. But I know some organizations that want to switch to IPv6 consistently and you can rephrase my question to whether Samba can accommodate these organizations. I do accept the answer that IPv6 was not available during provisioning, but how can one switch that? The obvious place smb.conf doesn´t show anything.
Thanks,
Joachim

I don't use IPv6, but I think it is one of the things that is checked during a provision or join. I have seen something like 'no IPv6 interfaces found, will not use IPv6 addresses' during either setup.

Do you need IPv6, do you have over 16 million network devices ? It might just be easier to turn off IPv6 on that DC.
