What privileges does 'k get ns' require?

We recently started to use ‘local’ (to the git repos) kubeconfig files, instead of the ‘global’ one under the user home directory.

One surprise is that whereas this works fine:

$ k --kubeconfig ./kubeconfig-admin config get-contexts
...

…this does not:

$ k  --kubeconfig ./kubeconfig-admin --context dev get ns
Error from server (Forbidden): namespaces is forbidden: User "notification-admin" cannot list resource "namespaces" in API group "" at the cluster scope

Is this intentional? What is the rationale?
There was no such restriction with the global kube configuration.

Thanks
Marc
