[keycloak-user] app-authz-photoz: error 403

Hello, I'm new to Keycloak and trying to follow the example in the keycloak-quickstarts: app-authz-photoz I've built and deployed photoz-html5-client and restful-api using the instruction in the Readme file. After I login using the specified credentials (alice or admin) I get error 403: You can not access or perform the requested operation on this resource Profile page does not display the name and I cannot create albums. Any clues or tips are greatly appreciated. Thank you in advance, Alex Rozenberg
