[Samba] ipv6 with Samba-AD-DC?

[Joachim Lindenberg]

I do have an AAAA record, otherwise my monitoring would just ignore IPv6.
I´d still like to know what configuration is used by samba-ad-dc to decide whether deamons listen on IPv6 (or both, fine) or just IPv4.

Hi all,

I sent an email on the mailing-list a couple of month ago about IPv6: 
https://www.spinics.net/lists/samba/msg180986.html
What I found when I tried was that there was no AAAA records for the AC-DC in the DNS.
I do not know if it is a general problem or whether it is was something in my configuration.
