One or more administrators can be sent notifications when a role is assigned to a user.
Specifying a notification recipient is optional. You could choose to notify an administrator if you decide not to require an approval when a role is assigned to a user. Or you could designate one administrator to serve as an approver, and, another administrator to serve as a notification recipient when the approval is made.
As with owners and approvers, notifications can either be directly added to a role, or dynamically added using a role-assignment rule. Notification recipients are notified by email when a role is assigned to a user. A work item is not created, however, because an approval is not required.
Notifications are assigned to roles on the Security tab on the Create Role form. Designating Role Owners and Role Approvers shows the Create Role form’s Security tab.
