In my experience as a Windows sysadmin, AD and HyperV are the big two.
I will espouse support for AD readily, it's very good at what it does and connects with M365 with minimal setup. HyperV is also a perfectly cromulent hypervisor, but in that space, They all serve the same function and none I've worked with really have a killer feature that sets it apart from the others.
That's why they EEE'd LDAP: vendor lock-in. It's MS.
Active Directory is a monster. Got downvoted to hell the other day for saying there is nothing out there that comes close for managing a fleet of machines. Most of the idiot arguments revolved around thinking AD is fancy LDAP.
"Linux and Mac can do authentication!"
If one's view of AD is that limited, we're not having the same conversation. Cross connect AD with Powershell and Hyper-V, you have a robust ecosystem for enterprise. And there are zero issues with running headless Linux servers on Hyper-V.
I have no experience in sysadmin work, but have some understanding of the Linux tools used. Can you eli5 what exactly is it that AD does? (Feel free not to, I just couldn't find a good article, so decided to ask.)
