The samba howto, is just that, a howto. It is not meant to be followed
to the exact letter.
Before you start to use the howto, you need to know what dns domain to
use, if you have a registered dns domain, it is not recommended to use
this, because if you do, your AD DCs & clients may be resolvable from
the internet. You are recommended to use a sub domain
i.e. if your registered domain is 'example.com', you would use
'internal.example.com' or 'samdom.example.com' or
'anything_you_like.example.com'.
Once you have decide what your dns domain is going to be called, you
must set the machine that the DC is going to be provisioned on, to use
this domain, give it a fixed ip, set /etc/hosts, make sure that
'hostname -f' returns the correct FQDN and 'hostname -s' returns
just
the short hostname.
Once you are sure that the machine knows who it is and where it lives
:-) , you can provision the domain with samba-tool using the DNS domain
as the realm name, the realm name *must* be the uppercase DNS name!
Now having said all this, it seems that the machines DNS name is
'internal.example.com' and the AD DC is using 'example.com'
If the machine you ran the tests on is the DC, it seems that this may be
your problem.
