[Samba] SAMBA_INTERNAL dns-backend limitations

[Anton Shevtsov]

Hi,

I see 
https://wiki.samba.org/index.php/Samba_Internal_DNS_Back_End#Limitations

The internal DNS does not support:

  * acting as a caching resolver
  * recursive queries
  * shared-key transaction signature (TSIG)
  * stub zones
  * zone transfers
  * Round Robin load balancing among DC's

but this was relevant for 2018-2019. What limitations remain now? For 
4.17.12 and 4.19.3
