Have you used windows before? It’s flaming garbage. Been using various oses for decades and I still rediscover how shitty windows is on the regular.
Yeah, and Linux still doesn’t have a good answer to AD for managing suites of end user machines. Linux has a lot going for it - but windows isn’t strictly inferior or anything.
Honestly, the entire AD suite with auth and everything else built in is genuinely a good product. And if what you want is supported by Microsoft, their other services are decent as well.
Notice how you’re ignoring the machine management and selectively choosing to focus on the user management. User management might be fine with Linux, but machine management can’t compete with GPOs, especially for managing Windows clients, which is what businesses are using for workstations whether we like it or not.
But if the windows fanboy doesn’t know about it, it’s not real. Or if it is, it’s not good! /s
