How to grant some users partial user management rights in Keycloak?

Question

Let's say I'm using one realm mycomp in Keycloak to handle all users (+ master realm for Keycloak superadmin).

I'm have role of Customer Support (CS) that should be able to view users and manage their basic data like names, email, password reset etc.

I'm able to grant realm-management permissions like manage-users or view-users to any user in 3 ways:

• assign directly
• by creating composite role for CS
• by creating group with and adding there CS

The problem is that giving manage-users rights CS end up being able to manage roles and groups so it is able to grant other users management permissions. Thats not valid for my config - it is a role of some higher level admin.

How to grant some users permissions to view and manage basic user data without allowing them to manage roles?

Answer 1

So in the end of the day I finally managed to find an working solution.

Problem was that Role manage-users cant be overriten by Policy.

With help of Pedro Igor Silva from Keycloak (https://issues.redhat.com/browse/KEYCLOAK-18151) I managed to setup configuration that fullfills the usecase.

With Keycloak preview feature admin_fine_grained_authz enabled I created global composite Role user-managers and granted it query-users Role from realm-management client. Then I created Policy that grants manage permission on Users resource when user has user-manager role.

That works perfectly
