set Custom properties from vCAC

Hi,

I am trying to provisioning a VM from vCAC. I want to set custom property such as "rootpassword" while provisioning.

How can I do that from vCAC. I am new to vCAC. Please help.

I have gone through this http://pubs.vmware.com/vCAC-60/topic/com.vmware.ICbase/PDF/vcloud-automation-center-60-custom-property-reference.pdf document, but I couldn't find.

Thanks
