I would like to be able to use auth0 as identity provider, so having all login part done through auth0 and using keycloak as authorization manager, so having all user permission management done through keycloak. Is there any way to do this ?
Yes there is.
Keycloak allows you to create mappers for custom identity providers, so that you can extract roles and attributes from your provider to keycloak. That way you will be able to use ABAC or RBAC in Keycloak, with still user permission management done through Auth0.
First you can add Auth0 as an identity provider through OpenID Connect or SAML2. Go to your Auth0 app config > advanced setttings > endpoints to get all the required information to create a new identity provider.
Then you need to create mappers in your identity provider, so you can import attributes or roles from Auth0 token. Documentation is available at https://www.keycloak.org/docs/4.8/server_admin/index.html#_mappers
Now your user in Keycloak will have attributes and roles you mapped from Auth0.
Next enable Authorization on your client. You can now define your resources, scopes, policies and permissions in it. See https://www.keycloak.org/docs/4.8/authorization_services/index.html

When an user account is disabled on a connected IdP, how do I ensure the account is blocked as soon as possible on Keycloak? At the moment, the “disabled” user is able to continue using my SPA because Keycloak continues to refresh the access token without speaking to the external IdP.
One of the critical features required by my partners when using SSO is that they have control over their users’ access to my application. At the moment if the user was logged into my SPA, they can continue using it for about 24 hours. I would hope to cut that time down to 5 minutes, the lifetime of the access token.
The external IdP is Google. I have tried using both Keycloak’s builtin Social provider for Google as well as setting up a SAML app in Google and user-defind SAML provider in Keycloak. I’m using Keycloak v9 but can upgrade if necessary.
Is there a recipe to achieve my goal? What options do I need to set in the Keycloak client and SAML provider?
Many thanks!
The approach could be as follows. The resource server will need to do the checking with the IDP, not Keycloak.
Enable the option to Store Tokens and Read Stored Tokens in the IDP settings.
Assign users the broker/read-tokens role.
On the resource server, decide on a frequency to check whether the user has been disabled on the IDP. Be aware of each IDP's token introspection's endpoint. Each time the API is consumed:
First of course verify the access token as usual.
If it's time to verify against the IDP, call the Keycloak API with the access token to retrieve the IDP's access token.
The Keycloak endpoint is: https://{domain}/realms/{realm}/broker/{idpid}/token
Call the IDP's token introspection endpoint to validate the IDP access token.
Act accordingly if the IDP responds that the token is not valid. Respond with 401 and ensure that the Keycloak access token can't be used again. Maybe the end_session_endpoint or revocation_endpoint, not sure.
Token validation endpoints:
Google: https://www.googleapis.com/oauth2/v3/tokeninfo?access_token={access_token}
AuthO: https://{tenant}.eu.auth0.com/userinfo
MS Azure: doesn't exist, good luck with that!
I am using Keycloak 18.0 for Angular 13 + Spring Boot App. The solution utilizes Microservices architecture pattern for this app so basically Keycloak already guards access to other solution resources. I am using only Keycloak REST API.
The problem is Keycloak security itself:
I want to restrict Keycloak client token only to user creation.
Any user has to be able:
1. Fully access and manage ONLY his own profile.
2. Has restricted access to profiles of other users.
3. Any other operation of viewing other users, adjusting
roles etc. should be enabled only if authenticated user
has some kind of permission to do it.
For example:
Anybody can create user (signup).
After user is verified, some role is assigned to that user.
User logs in and acquire its token that has permissions to fully manage only his own resources including user itself and has restricted access to other users and user resources.
I am not sure I want to integrate Keycloak as resource security manager (i am considering that option but for now, only Spring Boot Adapter was implemented to control corresponding resources security) but at least i would like to prevent e.g. reading full list of users using Keycloak client token.
I have basic understanding of Keycloak Resource/Policy/Permission Feature but I am not sure i understand how can i apply it to Keycloak users itself.
Thanks a lot in advance for your help.
I've successfully configured Keycloak as identity server for WSO2 api manager and I need am able to login to keycloak and, with the bearer, call a WSO2 defined rest API.
Now I need to make WSO2 send to the backend, also claims based on keycloak user's information, like role, group or property.
WSO2 apim 4.1.0 and Keycloak 19
You can't group information from access token's claims but you can get client role, realm role, user name, username and client name.
User group or group member can get by separate API call.
You need to start this order
create realm -> create client -> add realm role -> add client role -> add user (with credential) -> assign realm role to user -> assign client role to user
Then
get access toke for user with grant_type is "password"
decode access token by jwt.io
Finally can map between Keycloak settings and token's claims
You needs to understand how to access the resource by Role Based Access Control in Keycloak.
Here is good explain for Resources, scopes, permissions and policies in keycloak
I'm new to Keycloak and trying to find out if authorization services (Resource Server) can fit my requirements.
I have the following scenario: A client app is trying to access my API endpoints which are behind the API gateway. I want to authenticate (using id and secret) the app and if it's App A allow it access to the endpoint /credits, if it's App B allow it access to the endpoint /debits.
I assume that API gateway should verify if a call should be rejected or not.
Could you please tell me what should my workflow look like and what Keycloak functionality should I use?
I'd add roles CREDITS_CLIENT and DEBITS_CLIENT to the API_SERVICE realm in keycloak.
Then, I'd create app-a-service-account and app-b-service-account in that realm, the former with CREDITS_CLIENT role and the later with DEBITS_CLIENT role.
In the gateway or API controller, endpoint /credits requires role CREDITS_CLIENT and endpoint /debits requires role DEBITS_CLIENT.
On each call, check if the details in the jwt include the role that authorizes the account/user to access the endpoint.
I would like to configure Authorization within Keycloak.
Right now I have Keycloak working with Kong and OIDC plugin.
It works well without authorization, i.e., my page is accessible only to logged users. But I could not configure authorization to control who can access the web page.
In order to test with the less configuration possible, I enabled authorization for my Client in Keycloak, set the policy enforcement mode to "Enforcing" and deleted every authorization resources, policies and permissions.
As stated by the documentation, it should not allow anything.
I tried also to evaluate my test user, and he does not have right to access anything.
However, after login I'm redirected to my 'protected' page.
Am I missing something ?
Kong's OIDC plugin implements OpenId Connect spec only, it does not work with UMA authorization. Actually it is a hude topic and I suggest you to read Authorization Services article of Keycloak documentation first.
