[Samba] Can not delete reverse entry from DNS server using w2k16 dns tool

[Thomas Glanzmann]

Hello,
I just tried to delete a reverse entry from SAMBA internal DNS using the
DNS tool on a Windows Server 2016 as Domain Administrator and it failed:

I did refresh multiple times, and it is still here. I also can still
resolve it:

(infra) [~] host 10.101.98.5 10.101.0.1
Using domain server:
Name: 10.101.0.1
Address: 10.101.0.1#53
Aliases:

5.98.101.10.in-addr.arpa domain name pointer iaas-05.v101.hpvl.org.

I can delete it using samba-tool:

(infra) [~] samba-tool dns delete ad.v101.hpvl.org 101.10.in-addr.arpa 5.98 PTR iaas-05.v101.hpvl.org
Password for [Administrator at V101.HPVL.ORG]:
Record deleted successfully

And it is gone afterwards. Can anyone reproduce that?

Cheers,
	Thomas
