[Samba] Debian11 Samba backport and bind9

[Ingo Asche]

Hi Stefan,

I have exact that running: Samba 4.17.4 and bind 9.18 from the 
bullseye-backports.

I my case "samba_dnsupdate --verbose --all-names" runs without any errors.

As like 9.16 I use the "dlz_bind9_18.so" entry in named.conf.

If you need further information to compare just ask.

Regards
Ingo
