What I want to do is to authenticate ubuntu users across the network. I have already created the domain, what I need to know is how to log in the users, save their personal settings and stuff like that. I am portuguese so I'm sorry if I commit any grammatical or writing mistake.
I have tried to google how to do this but everything that I found was how to join a ubuntu client to a windows server domain and that's not what I want.
This is very important, please help me!!!
