User groups allow more specific access control and allow a user to be associated with multiple groups. This is useful when organizations access requirements overlap and only a sub group of users in an organization need access to a server. To use user groups first associate users with groups then associate the same groups to a server. Then attach the organization to the server. Once done only users in a group associated with the server will be allowed to connect. If a user is not in one of the servers groups or the user is not in any groups the user will not be able to connect to the server.
