Can't seem to find an answer that works. Scenario:
Have an instance of jira with ~300 users and has been used internally in the past. We Are working with a partner now who I need to have access to only their project. All I can think is to add all employees to a group and change permission schemes to allow browse projects to that group and then have the 3rd party be another group that can access the other project. Other suggestions are welcome but for lack of another option, anyone have a good way to add everyone to a new group?
