I am testing Keycloak authorization services in the admin console and I'm unable to understand why in the next example keycloak is authorizing a user (tested in the evaluate tab). this is my setup :
Created a realm test
Created a client democlient with Authorization Enabled on
Create the realm role Admin
Create the user adminuser and assign it to the Admin role
In the Authorization tab withing the client democlient:
In Settings -> Policy Enforcement Mode is set to Enforcing
Create 2 scopes: list and save
Create a resource Resource A with the 2 previous scopes
In Policies tab, create a new Role policy called Only admins where (of course) i only permit admins:
In Permissions tab, created a Scoped-based permission called permit only admins Resource A, list Scope:
And that's it. now i check in the evaluate tab this policy using the adminuser, role Admin, Resource A, Scope List:
success! everything is fine in the world!... except No.
checking again the policy with the adminuser, role Admin, Resource A, Scope save (a scope where I did not define any permission) Keycloak is again Authorizing this rule :/
i assumed that policy enforcement mode set to Enforcing will deny the access to scope save, from the documentation of keycloak:
The policy enforcement mode dictates how policies are enforced when evaluating authorization requests. 'Enforcing' means requests are denied by default even when there is no policy associated with a given resource. 'Permissive' means requests are allowed even when there is no policy associated with a given resource. 'Disabled' completely disables the evaluation of policies and allows access to any resource.
so... what i am doing wrong? how can i make that keycloak deny the access to the save scope? (obviously i can make a permission where i explicitly deny this scope. but i want that the default is deny as the documentation says)
Any ideas will be deeply appreciated.
I have found the Jira issue that reference this problem It's clearly a bug:
https://issues.redhat.com/browse/KEYCLOAK-9483
There is a patch that will come with the Keycloak version 9.0
https://issues.redhat.com/browse/KEYCLOAK-12438.
So we just need to wait for this release

Is there any way to restrict the access to the keycloak admin console at the level of groups or user roles? The way of restriction by ip (and undertow filter to block external access), unfortunately, does not quite suit me. I will be very grateful for any advice!
I tried to create roles for security-admin-console and realm-management clients, but it didn't work, all the users still have access to admin console.
It turned out, that the problem was because of realms' default groups. I checked them out and there was admin role by default in all the realms' default groups. For this reason, all imported from a third-party idp users had the admin role by default and had access to the admin console.
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 configured okta snowflake SSO. I assigned users as well. I configures scim which has permission to create users, deactivate users, sync password. After i configure scim i am having errors for existing users Automatic provisioning of user to app snowflake failed. Error while creating user. Conflict. Error reported by remote server. User exist with given user name. Same thing happening when I am assigning the app to existing user with same user name. Is there any way to fix it or is it best to remove scim.
In order for the merge to be successful, the login mapping needs to be exactly the same (the rest gets updated by okta). So make sure users can login via SSO first.
You also need to transfer ownership manually. Documentation provides this command:
use role accountadmin;
grant ownership on user <user_name> to role okta_provisioner;
Snowflake SCIM doc
I followed the steps mentioned in the below WSO2 documentation to use WSO2 IS as an Identity Server with WSO2 APIM.
I use WSO2 IS 5.3.0 and WSO2 APIM 2.1.0.
https://docs.wso2.com/display/AM210/Configuring+WSO2+Identity+Server+as+a+Key+Manager
I am able to access the carbon admin console in both the WSO2 IS and WSO2 APIM (in two ports)
https://localhost:9443/carbon/admin/login.jsp
https://localhost:9444/carbon/admin/login.jsp
When I use WSO2 IS console (9443) to change the user roles, most of the times it is getting reflected immediately, using the same access token. How can it be possible ? An access token is provided by WSO2 with some pre configured scopes. Within the same login session, even before the access token expires, If we change the roles of the logged in user, the roles changes are applied immediately and my access rights are changed ? Is it a valid ?
Assume a user "USER1" got an access token with privileged rights and he/she is able to access privileged APIs. Suddenly if the roles are changed and user "USER1" is assigned a normal user rights, and the user is not able to access the privileged APIs within the same login session. Is this how OAuth works ?
Please help me understand.
If I change the roles in WSO2 APIM (9444), the roles are not getting reflected immediately. Some times, it wait for the access token to expire and the gets a new access token. Sometimes, role changes are getting applied even before the access token expire.
What is the synchronization interval between WSO2 IS and WSO2 APIM, to sync the roles?
I couldn't find these roles in mysql db or ldap. Where are they stored in the backend ?
There are differences in IS as a key manager and the inbuilt key manager of API Manager. The key manager comes with API Manager is not a full fledged Identity solution. Hence its role to scope mapping, access control, etc. are somewhat limited in the point of view of Identity Management aspects.
Identity server acting as a key manager provides the full access control mechanism, hence the change in the role should affect fast as possible, even for issues keys. This is one of the reasons of using IS as a key manager.
Question 1
Ans:
Lets say a user has an admin right when he got the access token. The enterprise may decide the user has no longer needs this right and changes that on their LDAP. It should be reflected on key validation as fast as possible. Otherwise the user has continued access to the service as privileged user until key expires, which is undesirable. So the behavior is valid.
Question 2
Ans: Yes, API Manager is strong on managing APIs. However, it is not a use/role management system. Hence there will be considerable delay in reflecting the role change. So, make sure you use IS to manage the user/roles, etc. when your API Manager is configured with IS.
Where is your configured roles
It should be in WSO2UM_DB configured (UM_ROLE table), if JDBC user store is your primary UserStore.
I have been confused for a long time about how the user of kubectl being authorized. I bootstrap a k8s cluster from scratch and use 'RBAC' as the authorization mode. The user kubectl used is authenticated by certificate first, then it should be authorized by RBAC when accessing the api-server. I did nothing about granting permissions to the user, however, it is allowed to access all the apis(creating pod or listing pods).
Kubernetes has no built in user management system. It expects you to implement that part on your own. In this sense, a common way to implement user auth is to create a certificate sign request and have it signed by the cluster certificate authority. By reading that newly generated certificate, the cluster will extract the username and the groups it belongs to. Then, after that, it will apply the RBAC policies you implemented. In this sense, if the user can access everything, then it can be one of the following:
You are still using the admin user account instead of the newly created user account.
The user account you created belongs to an admin group
You did not enable RBAC correctly
This guide should help you with an easy example of user auth in Kubernetes: https://docs.bitnami.com/kubernetes/how-to/configure-rbac-in-your-kubernetes-cluster/
