IPv6 in Samba4 AD DC, it does not come up after a server reboot, it get
stucked, look:
---
root@ubuntu-ad-1:~# host -t SRV _ldap._tcp.tcmc.com.br
_ldap._tcp.tcmc.com.br has SRV record 0 100 389 ubuntu-ad-1.tcmc.com.br.
root@ubuntu-ad-1:~# reboot

See it?!
Now I'm doing:
---
root@ubuntu-ad-1:~# ps xfa
....

So, samba is stucked, I'm not seeing the others "samba" child process as
usual, then I tried:
---
root@ubuntu-ad-1:~# service samba-ad-dc stop
stop: Unknown instance:
root@ubuntu-ad-1:~# killall samba smbd
root@ubuntu-ad-1:~#
root@ubuntu-ad-1:~# service samba-ad-dc start
samba-ad-dc start/running, process 1446
root@ubuntu-ad-1:~# host -t SRV _ldap._tcp.tcmc.com.br
_ldap._tcp.tcmc.com.br has SRV record 0 100 389 ubuntu-ad-1.tcmc.com.br.
---
Back online!!
I believe that there is something wrong with the Samba4 init scripts
when we have IPv6 enabled.
Cheers!
