Setup as domain controller
samba-tool domain provision --use-rfc2307 --interactive --use-xattrs=yes
Argument Explanations
--use-rfc2307
this argument adds POSIX attributes (UID/GID) to the AD Schema. This will be necessary if you intend to authenticate Linux, BSD, or OS X clients (including the local machine) in addition to Microsoft Windows.
--use-xattrs=yes
this argument enables the use of unix extended attributes (ACLs) for files hosted on this server. If you intend not have file shares on the domain controller, you can omit this switch (but this is not recommended). You should also ensure that any filesystems that will host Samba shares are mounted with support for ACLs.
--interactive
this parameter forces the provision script to run interactively. Alternately, you can review the help for the provision step by running samba-tool domain provision --help
Setup replicator/secondary domain controller
Install and setup a server with the above but stop short of running the samba-tool domain provision ... cmd
Make sure you can use the nameserver the existing DC is using (ie point your namserver whatever the existing one is using).
Start replication:
samba-tool domain join HQ.SKYTECH.DK DC -Uadministrator --realm=HQ.SKYTECH.DK

Also I had some issues with DNS - make sure it is pointing to the ip of the machine running samba.
