samba - Aug 2017 - IPv6 link-local address support with Samba4

Hello Samba Community,

I've couple of questions regarding IPv6 link-local address support with
Samba4.

Is Samba4 suppose to listen on IPv6 link-local address?

With following lines in smb.conf, smbd listens on IPv4 and IPv6 global
address but not on IPv6 link-local address assigned on eth0.
        bind interfaces only = yes
        interfaces = lo eth0

On the same Linux box, Samba-3.5 used to listen on IPv6 link-local address
as well. Is this a bug in Samba4?

Further, by setting "bind interfaces only = no" in smb.conf, smbd
listens
on IPv6 wildcard address. However, the point and print operation fails
using IPv6 link-local address. It throws up "Operation could not be
completed error 0x00000709" on the client. The smbd log says OpenPrinter
error.
_spoolss_OpenPrinterEx: Cannot open a printer handle for printer
\\<ipv6.linklocal.addr>.ipv6-literal.net

Is OpenPrinter suppose to work with IPv6 link local address on Samba4? This
used to work fine with Samba3.5.

Thanks,
SambaUser

Hia, 


If you setup for ipv6, is hostname resolvable (AAAA and PTR), and if the ipv6
number
and hostname also added on the localservers /etc/hosts
