[Samba] Problem trying join Samba 4.18 to Windows AD

[Miguel Angel Coa M.]

Hi,
I have Rocky Linux 8 with Samba 4.18.6 compiled, and trying join to Windows
Server AD 2012 DC (2008 R2 function level).

1. sambadc05.domain.cl is the Samba 4.18.
2. windowsdc01.domain.cl is the Windows Ad.

[..............................]
PS C:\Windows\system32> Get-ADForest | Fl Name, ForestMode
Name       : domain.cl
ForestMode : Windows2008R2Forest
[..............................]

But i've the next error after a few minutes and sync process:

[..............................]
Replicated 139 objects (0 linked attributes) for DC=mydomain,DC=cl

For join used the next command:

[..............................]
samba-tool domain join mydomain.cl DC -U "mydomain\administrator" --realm=
MYDOMAIN.CL -W MYDOMAIN --server=windowsdc01.mydomain.cl --password=secret
--dns-backend=BIND9_DLZ -d3
