Description of feature: At the moment it is not possible to see all existing users for a domain. At the moment only online users can be selected/shown. It should be able to turn this feature on and off through the domain config. Motivation: (Why?) This feature would be very helpful for admins. I know that for huge domains with tons of users the query would maybe kill the server or the client where the result is shown. So the feature should either only show the first X users (the value should be able to set in the config) or maybe turned off completly in the domain config.

highly need
