[Samba] Problems with samba 4.6.3

[Marcio Demetrio Bacci]

I have two DC with Samba 4.2.1 and now I have set up a third DC with Samba
4.6.3. I have executed the command: samba-tool domain join empresa.com.br
DC -U "EMPRESA\administrator" --dns-backend = SAMBA_INTERNAL

And everything went well, however with the command: samba-tool drs showrepl

The following message appears:
