Well if Zorin gets their product out ever, it is Zorin Grid. Until then I see opensuse has AD support https://doc.opensuse.org/documentation/leap/security/html/book-security/cha-security-ad.html

As for clients their is Leap/tunbleweed autoyast to capture an install setup and replicate to new installs. Or if you choose MicroOS it’s a config file you use at first boot to set user, apps, settings etc

But I’m hoping Grid will become an all in one management system Zorin promises
