I am wondering if I can/should enable domain auth for my ESXi 6.5 free since my domain controller is on my ESXi host. Would I run into any issues with this potentially? Also is there say a backup login method?
Do you need to for some reason? It's probably not the best idea ever, so yeah, you'd run into issues if your DC was down and you couldn't login with even root. Reduced complexity is always better.
Was just an idea to move towards having one login for everything instead of many logins.
As long as you have a potential chicken-and-egg scenario on your hand, I would avoid it.
I guess I could set up a DC-1 and DC-2 system with DC-2 on a different host.
That would be preferable. I would say use anti-affinity rules to keep them separate, but with ESXi free and no vCenter that's not an option (not that vMotion is anyhow).
I am getting the VMUG subscription to solve a few of my problems just not sure when. I will note that for when I have licences that work worth a dam for more than the basics. Though the free version is great for lots too
You can use AD authentication with ESXi host it's better to give limited privilege to AD users instead root privilege.
