userarn should be the key instead of userARN

Under mapUsers, userARN should be replaced with userarn. kubectl doesnt add the user if the key is userARN

Having integrated with KOPS without any issues since v0.1.0, I just ran into this very problem when deploying the same ConfigMap that we were using with KOPS to an EKS cluster (v0.3.0). Took a long time to figure out. Has the configuration changed?

[christopherhein]

It's actually a configuration difference between EKS and the OSS aws-iam-authenticator. We're in conversations about changing the loading of these roles using CRDs instead check out - #116 for more information on that.

For now the OSS distro still uses the userARN & roleARN and EKS uses userarn & rolearn.

Closing this, as @christopherhein said, its a (confusing) difference between OSS and EKS authenticator. Were working on moving to the OSS configuration, but for now, EKS users should refer to the EKS docs.
