[Samba] Bind9 doesn't updated - TSIG error with server: tsig verify failure

Hello everybody,

I've had a samba environment with the following "brief"
description:

   - There are 2 DC (*samba4 *and *samba4bkp*) running samba version 4.1.6
   on my domain (*SMB*). DNS back end is Samba Internal DNS;
   - I've added a new DC (*king*) running samba version 4.10.2 and  as DC
   to *SMB *domain with BIND9 DNS Back End;
   - *king* has updated dns zones and I've checked it;
   - *king *has got resolve *SMB* domain names;
   - *samba4bkp* has broken and I've lost its disks. Then I've followed
   steps described on
  
https://blogs.technet.microsoft.com/canitpro/2016/02/17/step-by-step-removing-a-domain-controller-server-manually/
to
   remove *samba4bkp* manually.

After remove *samba4bkp, *I've checked *samba4* dns zones and they are ok,
but *king *still has maintained *samba4bkp* registers. Then I've tried to
update dns entries running *samba_dnsupdate --verbose --all-names* and it
has returned that all 28 entries failed to updated, as shown below.

I've searched about similar error "; TSIG error with server: tsig
verify
failure", but I've been unsuccessful.

Regards!

It looks like it isn't: 'Successfully obtained Kerberos ticket to

'king' is using the 'samba4' such as its nameserver. I've

that 'king's ticket has expired at 04/26/2019 (this is the date when
I've
created 'king' and add it as a DC on SMB). After this, I've obtained
a new
Kerberos ticket with 'kinit' command, but 'samba_dnsupdate --verbose
--all-names' has returned the same problem I've reported.

OBS: Shouldn't DC renew Kerberos ticket automatically?

Regards!
