Vault kubeauth with OpenShift

Hello ,

We’ve enabled Kubeauth on vault and hooked the Openshift service account for secrets retrieval. following below documentation
Kubernetes - Auth Methods | Vault | HashiCorp Developer.

However this solution works fine for a given service account in a namespace.
we are looking to have this solution implemented on multiple open shift clusters having multiple service accounts and namespaces.

could you help in tackling this.
