To ensure that the correct Keycloak user roles are assigned in Superset after integrating Single Sign-On with Keycloak, you need to map the roles from Keycloak to Superset roles using the AUTH_ROLES_MAPPING configuration. It seems like you have already set up the AUTH_ROLES_MAPPING in your superset_config.py, but the issue might be with how the roles are being extracted and used.

Here are a few things to check and adjust:

1. Role Extraction: In your CustomSsoSecurityManager, ensure that the roles are being correctly extracted from the Keycloak response. The oauth_user_info method should extract the roles from the correct field in the Keycloak response. It seems like you are using role_keys, but you should verify that this is the correct field in the Keycloak response.

2. Role Mapping: Make sure that the roles you are mapping in AUTH_ROLES_MAPPING match exactly with the roles being sent by Keycloak. Any mismatch in role names will result in the default role being assigned.

3. Debugging: Add logging to verify what roles are being received from Keycloak and how they are being processed. This can help identify if the roles are being correctly extracted and mapped.

4. Sync at Login: Since you have AUTH_ROLES_SYNC_AT_LOGIN set to True, roles should be synced at every login. Ensure that this setting is being respected by checking the logs for any errors during the login process.

If these steps do not resolve the issue, you might want to review similar discussions for additional insights. For instance, there is an open discussion on Assigning Superset roles to Keycloak authenticated users using the AUTH_ROLES_MAPPING that might provide more context or solutions ^[1].

@dosu when i print data = me.json() i get this

{'sub': '182345b0-c8a1-1233-2da2-c22afe2b882c', 'email_verified': True, 
    'name': 'Abc def', 'preferred_username': 'abc@gmail.com',
 'given_name': 'Abc', 'family_name': 'def', 'email': 'abc@gmail.com'}

there is no role_keys

To correctly extract roles from the Keycloak response, you need to ensure that the roles are included in the response from Keycloak. It seems that the current response does not include any roles. Here are some steps you can take:

1. Configure Keycloak to Include Roles: In Keycloak, you need to configure the client to include roles in the token or userinfo response. This can typically be done by adding a mapper in the Keycloak client settings. You can add a "User Realm Role" or "User Client Role" mapper to include roles in the token.

2. Update oauth_user_info Method: Once roles are included in the response, update the oauth_user_info method to extract the roles from the correct field. For example, if roles are included under realm_access in the token, you might access them like this:

   roles = data.get('realm_access', {}).get('roles', [])

3. Verify Role Mapping: Ensure that the roles extracted from Keycloak match the roles defined in your AUTH_ROLES_MAPPING configuration.

By configuring Keycloak to include roles and updating your code to extract them correctly, you should be able to map Keycloak roles to Superset roles effectively.
