The documentation provided with this Beta release incorrectly states that if you do not enable vCenter SSO, a default administrator credential is used, which you can change at a later time. In fact both the Big Data Extensions plug-in installed within the vSphere Web Client, and the Serengeti Command-Line Interface console will fail to authenticate if SSO is not enabled.
This document instructs you on how to successfully deploy Big Data Extensions on vSphere 5.1 and later by enabling vCenter Single Sign-On.
