User access is granted to services based on permission levels. for instance, if you have a bowling web site called Bowl4Beer you could create a service called Bowl4Beer using the Uma admin tool. Now all you need to do to protect your site from unauthorized bowlers is simply edit the authenticator.php file and set the $serviceId to correspond to the 'id' column in the Service table for the Bowl4Beer record. The 'id' for Bowl4Beer will appear in parentheses in the admin tool next to service name.
