It is more than that, I have just set up a test DC on Almalinux 9 and,
as my ISP does not use IPv6, I have no reason to use IPv6 (I do not
have anything near 16 and half million dns clients). I attempted to
turn off IPV6 on Almalinux using the old method of adding
'ipv6.disable=1' to the 'GRUB_CMDLINE_LINUX' line in /etc/default/grub
, it didn't work. After a bit of investigation, I turned up the
'grubby' command, after using this, IPv6 was turned off.
So the question is, has the OP actually turned of IPv6 ?
From what the OP has posted, in my opinion, he is doing everything
wrong. I am not talking about using the fedora 41 Samba packages for the
DC (though I wouldn't recommend this), what I am referring to is using
the freeipa tools with Samba. I personally would never attempt to join
a computer running Samba using realmd and I certainly would never run
sssd on a Samba computer. If you just want authentication from AD, then
sssd is great, but for shares you need smbd, at which point you require
winbind and there is no point in running sssd and winbind, they both do
virtually the same thing.
