Abstract
Example techniques described herein involve authorization management in a media playback system. Within examples, a client, such as a control device, may authenticate with a playback device using a token. The playback device may resolve a role corresponding to the token using a token-to-role mapping hosted at an authentication service. After resolving the role, the playback device may resolve a permissions set corresponding to the role using a role-to-permissions mapping similarly hosted at the authentication service. Within examples, such mappings may be cached locally at the edge (e.g., on a playback device).
