User properties are modified by selecting the user's row in the list of users displayed in the Users tab. The user properties are displayed on the right.
After properties have been changed Apply Changes must be selected to commit the changes to the server.
Multiple users can be selected from the list of users by using the combination of the control key and left button click. The properties panel displayed can be used to set properties for all of the selected users.
Multiple users can also be selected via the right mouse button menu item, Select. All users can be selected, or users from a particular group or matching a wildcard.
Groups can be quickly added/removed from this menu as well, using the Groups menu item. Besides, the Manage Groups dialog box can be accessed from here. See How to manage groups for more details.
