I am from a small primary school and we are currently looking into getting a server purely for authentication. I do not want to push software to the devices or anything like that. I simply want to force the devices to input a username/password before they can use it (to keep track of who is using what for security purposes. We are getting more and more windows tablets in and it is hard for the teachers to keep track of who is using what).
I do not want to spend money so i thought using open source server software would be a better idea. I understand i will need a relatively good piece of hardware to then run this but that shouldn't be a problem to sort out.
I looked around at Apache, ClearOS and Ubuntu Server and they all look great but i can't seem to find any information regarding compatibility of Linux servers with windows.
So: Is it possible/practical to use a Linux server to authenticate Windows devices? and if so, any recommendations?
