The target is to replicate a MS AD DC (Windows server 2012) to a new Samba4 AD DC, then migrate users to the new Samba domain. This is our first time, and the various documents on the Internet are not very encouraging.
There is only one forest and a unique AD DC.
The concern is to ensure all necessary objects from the original AD DC will be copied to the new Samba directory.
The Samba wiki page, Join a domain as a DC, clearly indicates that the "join" will work only for Windows Server 2008 R2 at most (we have a 2012 version). It is then probably better to start from scratch on Samba, importing the various MS AD objects from a script / samba-tool
.
What are your recommendations, warnings, to achieve a MS 2012 AD DC to a Samba 4 AD DC migration, and in particular how to ensure the maximum of the information from the Windows machine can be transferred to Samba4, in other words, generate the least inconvenience to the users.
