Have you started Samba ? The ntp_signd isn't created until you do.

That, in my opinion, would be a bad idea, 24.04 is an LTS version and
25.04 isn't and will go EOL next January.

Then the order of the steps on the samba website should be changed maybe,
why would it talk about setting up chrony first before doing the samba and
ad join stuff.
I wanted to use an distro that had a higher version of samba in it. i
understand about the lifecycles but was just going to do the upgrades when
its required.
CAn you please help suggest the correct process for upgrading the forrest
and domain level?
