Hi @joeeltgroth,

Please sign the CLA which is required to merge this PR and we need two thumps up or approvals from approver in the Credhub WG area.

See comment in #1036 (comment) for details about how to sing the CLA.

I have made my membership public here: https://github.com/orgs/pivotal-cf/people?query=joeeltgroth
Do I now need to sign the CLA again? When the CLA dialog asks what company, what do I enter in to map it to pivotal-cf?

@beyhan @rkoster I have gotten the EasyCLA authorization. Could this now be approved?
