# Keycloak SSO for Kubernetes

Check the Helm information [here](https://artifacthub.io/packages/search?repo=open-metadata).

Here is an example for reference, showing where to place the values in the `values.yaml` file after setting up your Keycloak account and obtaining the application credentials.

Check the more information about environment variable [here](/deployment/security/configuration-parameters).

{% note %}

Altering the order of claims in `jwtPrincipalClaims` may lead to problems when matching a user from a token with an existing user in the system. The mapping process relies on the specific order of claims, so changing it can result in inconsistencies or authentication failures, as the system cannot ensure correct user mapping with a new claim order.
