Realm Roles
Realm-level roles are a global namespace to define your roles. You can see the list of built-in and created roles by clicking the Roles left menu item.

To create a role, click Add Role on this page, enter in the name and description of the role, and click Save.

The value for the description field is localizable by specifying a substitution variable with ${var-name} strings. The localized value is then configured within property files in your theme. See the Server Development for more information on localization. If a client requires user consent, this description string is displayed on the consent page for the user.
If the client has to explicitly request for a realm role, set Scope Param Required to true. The role then has to be specified using the scope parameter when requesting a token. Multiple realm roles are separated by space:
scope=admin user
