Setting permissions for a user

Hi,

I’m currently working on a project about openHAB.
openHAB stable 3.x is running on a Ubuntu Server LTS within a virtual machine.
Is there any possibility to give a user read, write or edit permissions? Couldn’t find anything about it.

Thank you in advance.
Jacky
