Frequently asked questions ​

Can realms be organized in a hierarchy (realm in a realm) ​

There is no realm hierarchy as they all stand at the same level with a strong isolation. If hierarchy is a requirement then leverage "groups" instead.

How to impersonate (a user with specific rights that connect as another user) ​

Keycloak offers out of the box support for impersonation.

Cloud-IAM support team can help set impersonation if the customer has issue with the official documentation.
