DIsk Change Tracking - Veritas Agent

I'm trying to configure Veritas agent for VMware and see in the pre-reqs the following :

* Note: Apart from Disk Change Tracking, the above permissions are by default all included in the "VMware Consolidated Backup user (sample)" role

What permissions are needed to properly use the Agent for VMware Virtual Infrastructure (AVVI) with Backup Exec 2010 and…

Where or how can I enable DIsk Change Tracking on the VMware Conslidated Backup user role ?  I can see it listed at all when I edit this role.

6.7.0 Update 1 (10764712)

Thanks.
