vCenter 5.1 lab environment without AD

Hi guys,

I am attempting to perform a sanity check of our vCenter 5.1 server to the most recent version of 5.1.  To accomplish this I have created an isloated lab and cloned the production vCenter and its SQL back-end machine into it.  They have connectivity to each other however vCenter services will not start.

I strongly believe that this is because SSO requires AD in order for the vCenter services to start, however I do not have AD in my islolated lab.

Is there any way to accomplish this without bringing a production AD controller into the lab?

Thanks.
