First (I have to point this out, fedora doesn't), the default Samba
packages to create An AD domain on fedora use the MIT kdc, this is
still classed as experimental, so they shouldn't be used in production.

You seem to have created an AD domain, but then went on to use tools to
create users, groups and computers from an NT4-style domain, why did you
not use samba-tool as shown on the fedora page you linked to ?

Unless ntpsec has fixed its NTP server (and I haven't heard if they
have), it doesn't work with a Samba DC, so I would suggest only using
Chrony.

Now we come to the 'biggy', do you know by having this line in your
smb.conf:

server services = ntp_signd

You have turned everything else off ?

I would remove it and restart Samba.

I would also remove the spurious machines you have added to
/etc/passwd, that is not where they live and how you join them.
