RBAC config in values.yaml:

## Authentication parameters

auth:
  ## Role-based access control parameters
  ## ref: https://etcd.io/docs/current/op-guide/authentication/
  ##
  rbac:
    enabled: true
    ## @param auth.rbac.create Switch to enable RBAC authentication
    ##
    create: true
    ## @param auth.rbac.allowNoneAuthentication Allow to use etcd without configuring RBAC authentication
    ##
    allowNoneAuthentication: true
    ## @param auth.rbac.rootPassword Root user password. The root user is always `root`
    ##
    rootPassword: "admin"
    ## @param auth.rbac.existingSecret Name of the existing secret containing credentials for the root user
    ##
    existingSecret: ""

I kubectl exec in etcd pod, and run command etcdctl user get root and got error msg:
