Vault kubernetes auth backend multi cluster

I wish to configure one auth backend (e.x dev) with multiple clusters that can authenticate to that auth backend. this could be useful for a blue and green clusters that need to access dev auth backend.
For some reason i can’t get it to work.
Is this even possible?



But you can configure multiple auth backends, so choosing to mount one kubernetes auth method for each cluster, at paths which embed the name of the cluster that they work with, is a common pattern.

Yeah i wanted to avoid that, but i guess thats what i would do.
Thanks @maxb.
