Problem: I have few systems which run the same version of Ubuntu (i.e. 16.04) on my lab network. Currently all terminals have their own local users. Terminals are not uniquely assigned to a user. So a user can login into any available terminal. The problem is creating new user in each system with same password on each of these terminals. Required Solution: I need a way so that I create a user on the server (one of the system/terminal will be assigned if required) and then the users can login any of these systems using that account.
I have tried searching on internet but I couldn't find the technical name for the service I am looking for. Thanks in advance
