Hi All,
I am using the same DNS configuration for 12.2 and it is no longer working with 18c. I got the following error:

Is it the new security enhancement added to 18c? Where do we specify the privilege delegation? (given I have none in my lab environment)
environment:
OEL 7.5 x64 (min install + 18c pre-install rpm)
Grid Software 18c
Network setup
database server: bedorcl.pojencrossing.localdomain, 192.168.2.70 (configured as domain cluster)
dns server: netsrv.pojencrossing.localdomain, 192.168.2.60
dns-glue record: gns.pojencrossing.localdomain, 192.168.2.61
