I have always been exposed to windows active directory with server controlled logins, server based "home" directories, etc. With the nature of NixOS it seems like it might be easy to deploy something similar by just setting up the configuration.nix as some sort of symlink to one stored on a central server. The only issue would possibly be how to not create home directories on the local machine and instead store them on server. You might be able to make a central passwd file that gets read, but i am not sure just how secure that would be. Thoughts?
