[Samba] IPV4 Only Environments Kpasswd5 Port 464 Not Showing when ipv6.disable=1 on Kernel CLI

[Gregory Carter]

I noticed that kpasswd5 (port 464) isn't showing up on subnets where IPv6
is not allowed.

So I cannot do any joins for these Linux boxes.

Is there a Global switch I can use for samba to just startup and listen on
IPV4 only?

It seems inconsistent as all the other services don't seem to be affected
by this switch and appropriately bind to the interface.

How do I get kpasswd5 up on IPV4 only?
