User attributes are extraordinary capabilities, limitations, or environments that can be assigned to a user either all of the time or when the user is connected to a specific group or groups. When an attribute is to apply all of the time, it is specified at the system level and is called a user attribute. When an attribute is to apply only to a specified group or groups, it is specified at the group level and is called a group-related user attribute. For example, user attributes that you specify in an ADDUSER or ALTUSER command are stored in the user's profile and are in effect regardless of the group to which the user is connected.
