[Samba] Problems joining Samba 4 in the domain

Hi

As described in (
https://wiki.samba.org/index.php/Distribution-specific_Package_Installation)
I haven't installed the follows packages: libpam-winbind libnss-winbind
libpam-krb5

Can this be the problem?

>The whole point behind 'samba_dnsupdate' is to check a list of records 
that should be in AD for a DC and create them if they do not exist, so 
how can trying to create a record that already exists be an error ?

I will check the python code and see I can work out what is going on.

No, they are the packages required (along with /etc/nsswitch.conf mods) 
to make 'getent' work and are not required on a DC.
