Sisyphus is designed as a project to provide a simple solution for managing authentication/authorization of many kubernetes clusters.
X509 Client Certificates may not be the best practice for authenticating clusters, please refer to Official Document for other practices.
You can simply give three variables: user names (can be given multiple names with using commas), group name (should be predefined) and target cluster name.
We can list the users and related cluster/rolegroup informations.
