Hello, wonderful people!
I am trying to set up two domains: a.domain.com and b.domain.com. The reason for having two domains is that one is for Active Directory, and the other is for the Linux domain using RHEL IDM.
The Windows server serves as the DHCP server, with the domain controllers' IP as the first DNS and the IDM controllers' IP as the second DNS. Both domains have a forward zone set up to point to the other domain, and this configuration seems to be working nicely so far.
Now, the issue: Let's say I have clients client.b.domain.com and client2.b.domain.com. They have successfully joined the IDM domain, but neither can ping each other's hostname nor perform an nslookup on it.
I also notice in the Windows DHCP server that the clients' FQDN is client.a.domain.com and client2.a.domain.com, even though I have set them to b.domain on the clients themselves.
Any ideas on how or what I need to change to get local hostnames working in this scenario?
Hey thank you for the very detailed response! I can not give a full response right now. But the hacky way described is exactly what i did and didnt seem to work for me.
