This field allows you to choose a ‘Service Profile’ for this user. A Service Profile describes a common set of RADIUS attributes shared by all the users with that profile. Your RAdmin Administrator will generally set up a separate Service Profile for each category of users your organization supports. If you select a Service Profile for a user, then the attributes from the Service Profile will be used to check and configure this user when they log in. User-specific attributes entered into this Edit User page will override the attributes from the Service Profile. If you choose the blank Service Profile, then there will be no Service Profile for this user, and their login attributes will be controlled by this Edit User page.
