Guys,

I'm trying to deploy Samba4 AD DC with IPv6 and I'm facing a hard time (LP #1335502)... First, it didn't worked "as-is", now, after enabling IPv6 in Samba4, it doe 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

Broadcast message from administrativo@ubuntu-ad-1
 (/dev/pts/2) at 22:10 ...

The system is going down for reboot NOW!
root@ubuntu-ad-1:~# Connection to 192.168.15.221 closed by remote host.
Connection to 192.168.15.221 closed.

tmartins@zion:~$ ssh administrativo@192.168.15.221

Host _ldap._tcp.tcmc.com.br not found: 3(NXDOMAIN)
root@ubuntu-ad-1:~#

Then, I tried:

---
root@ubuntu-ad-1:~# pidof samba
675

root@ubuntu-ad-1:~# pidof smbd
791 719

root@ubuntu-ad-1:~# host -t SRV _ldap._tcp.tcmc.com.br
Host _ldap._tcp.tcmc.com.br not found: 3(NXDOMAIN)
---

See it?!

Now I'm doing:

---
root@ubuntu-ad-1:~# ps xfa
....
  461 ? S 0:00 avahi-daemon: running [ubuntu-ad-1.local]
  462 ? S 0:00 \_ avahi-daemon: chroot helper
  675 ? S 0:00 samba -D
  719 ? Ss 0:00 \_ /usr/sbin/smbd -D --option=server role check:inhibit=yes --f
  791 ? S 0:00 \_ /usr/sbin/smbd -D --option=server role check:inhibit=yes
  728 ? Ss 0:00 /usr/sbin/cups-browsed
  745 ? S 0:00 upstart-file-bridge --daemon
....

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!
