Re: [keycloak-user] Keycloak logout not working for “bearer-only” application exposing REST services

Hello, Thank you for your quick response. I am using keycloak-3.4.0 and wildfly-10.1.0.Final. I have just added on github the projects I have created for working with keycloak. You can find them here: https://github.com/NemesDan/keycloak Please note that these projects have been started as a POC of how keycloak can be used so there are other functions that are out of the scope of the problem I'm having. I am still in the learning phase of how keycloak can be used at it's full potential. NemesDan/keycloak keycloak POC projects <https://github.com/NemesDan/keycloak> There are multiple maven projects on this branch. 1. Project GSDKeycloakProject with 3 modules: customer-app, product-app and database-service. The last mentioned module is the bearer-only application in which the REST services are implemented. database-service: contains two classes ProductService and CustomerService which implement REST services that are accessible only to logged users that have the correct role assigned. 2. KeycloakAccess - should be ignored, out of the scope of the problem 3. RestClientApplication - a maven web project in which the entire workflow is implemented. This simulates a client application that will login a user using keycloak, retrieve a token and use that token to access the "database-service" bearer-only application. In class RestService you can find the following implemented REST web services 3.1 GET request on *http://localhost:8080/TestRestProject/rest/service/login <http://localhost:8080/TestRestProject/rest/service/login>* -> redirects user to the keycloak login page to perform the login. After login, keycloak redirects the user to to *http://localhost:8080/TestRestProject/rest/service/user_logged_in <http://localhost:8080/TestRestProject/rest/service/user_logged_in> .* At this point the code is exchanged for token. 3.2 GET request on *http://localhost:8080/TestRestProject/rest/service/call_database/{param} <http://localhost:8080/TestRestProject/rest/service/call_database/%7Bparam... - *{param}* could be either *products *or *customers* * - *this web service call will use the token from step 3.1 to access the database-service bearer only REST services 3.3 GET request on {URL}/logout or {URL}/logout_2 - these requests were created in order to test the logout functionality but it seems that the database-service REST services are still accessible after the logout has been performed which after my knowledge means that the token has not been invalidated The key point of these projects is to avoid using any keycloak classes to implement the client application because we do not want to force the clients to use a specific library. If I missed something please let me know. I appreciate your help.

Which adapters are you using for the client and bearer-only apps ? We need this info. And yes sharing your project (through github for instance) could be really helpful.

The logout works for a "confidential" applications but it doesn't for a "bearer-only" application (the REST services are still accessible after logout). I have the following configuration: - I have one "database" client application defined in Keycloak having access type "bearer-only" (created with the intent of exposing REST web services protected by Keycloak based on user roles) - I have one "rest_service" client application defined in keycloak having access type "confidential" (created with the intent of logging in users and allowing access to the "bearer-only" REST services after a successful login). The below described workflow is implemented in this application using REST web services I am performing the following steps: - An http GET request is performed on URL http://localhost:8180/ auth/realms/demo/protocol/ openid-connect/auth <http://localhost:8180/auth/realms/demo/protocol/openid-connect/auth> which redirects the user to the login page handled by Keycloak - The user performs the login using his credentials (using the credentials of a user defined in Keycloak) - Keycloak redirects the user to the "redirect_uri" which was passed in step 1. In this step Keycloak also provides as request parameters the "state" and "code" values. - After the user has been redirected back to the application I exchange the "code" received in step 3 for a token doing a POST request on http://localhost:8180/auth/ realms/demo/protocol/openid- connect/token <http://localhost:8180/auth/realms/demo/protocol/openid-connect/token> which is done successfully - After the access token is available I proceed to access the "bearer-only" REST web services. note: the REST web services exposed by the "bearer-only" service are not accessible unless the user has been logged in and it has the correct "role" assigned to it.Problem: As stated at the start of the post the user is still able to access the "bearer-only" REST web services after the logout has been done. The only thing that seems to work is the logout from the "confidential" application (the user is not able to access the application unless he logs in again).If I perform the logout of the user then the REST web services exposed by the bearer-only application are still accessible. In the Keycloak server I get the following WARN message: " Some clients have been not been logged out for user adminuser in demo realm: rest_service"I tried implementing the logout in three ways: - A redirect to URL http://localhost:8180/ auth/realms/demo/protocol/ openid-connect/logoutpassing <http://localhost:8180/auth/realms/demo/protocol/openid-connect/logoutpass... in the redirect_uri and client_id parameters - A POST request to http://localhost:8180/auth/ realms/demo/protocol/openid- connect/logoutpassing <http://localhost:8180/auth/realms/demo/protocol/openid-connect/logoutpass... in the Authorization Bearer in the header and the client_id, refresh_token, client_secret and redirect_uri - A REST service exposed by the "bearer-only" service which does the following method call: HttpServletRequest request.logout() Neither of the above methods is working.PS: I did not want to go in to many details because even so the post is long enough. If I missed something please tell me and I will provide the additional information (if possible I can also attach the actual projects) Thank you,Dan Nemes | | Virus-free. www.avg.com | ______________________________ _________________ keycloak-user mailing list keycloak-user(a)lists.jboss.org https://lists.jboss.org/ mailman/listinfo/keycloak-user <https://lists.jboss.org/mailman/listinfo/keycloak-user>
