[Samba] Unable to Join the Active Directory as a Domain Controller




Hello,

I am trying to use Samba in version 4.7.0 as a replication of an Active
Directory running on Windows 2012-R2.

For that, I execute the process described on this page:
https://wiki.samba.org/index.php/Joining_a_Samba_DC_to_an_Existing_Active_Directory

When I run the command to join the domain controller, samba-tool returns
the following error:
DsAddEntry failed with status WERR_ACCESS_DENIED info (8567,
'WERR_DS_INCOMPATIBLE_VERSION')

I read the documentation that specifies which version of Samba is
compatible with the version of the Active Directory schema:
https://wiki.samba.org/index.php/AD_Schema_Version_Support

I was able to check on the Windows 2012-R2 server that the Active
Directory schema is in version 69, so theoretically compatible with
Samba 4.7.

User "MYDOMAIN\marcori" is a domain admin.
Do you have a way to explore further?

Respectfully,

Marc-Henri Pamiseux

PS: Here is the command invoked and its error message:
