Every edu ive worked with using Linux rolls an ubuntu derivative which has for six LTS versions supported easy AD integration. Smaller subsets just use Ansible + AWX but they are typically just manging the basics.
The AD integration on Linux is just getting you login. It doesn't support much local configuration of the endpoints, which is the killer feature of AD. I have also found the AD PAM modules to be a bit fragile. I keep having machines that work for awhile, then suddenly need 5 minutes to log in or simply can't log in at all after some time. It has been kind of frustrating for me. I want to tell people "just use your domain login, it will work", but its a lie too often.
