View and XenDesktop vCenter Permissions

Both VMware View and Citrix XenDesktop require permissions within vCenter to provision and manage virtual desktops.  VMware and Citrix both have documentation on the exact permissions required for this user account.  Creating a service account with the minimal amount of permissions necessary, however, can be cumbersome and as a result, many businesses have elected to just create an account with “Administrator” permissions within vCenter.  While much easier to create, this configuration will not win you any points with a security auditor.

To make this process a bit easier I’ve created a couple quick scripts, one for XenDesktop and one for View, that create “roles” with the minimal permissions necessary for each VDI platform.  For XenDesktop, the script will create a role called “Citrix XenDesktop” with the privileges specified here.  For View, that script will create a role called “VMware View” with privileges specified on page 87-88 here.  VMware mentions creating three roles in its documentation, but I just created one with all the permissions necessary for View Manager, Composer and local mode.  Removing the “local mode” permissions is easy enough in the script if you don’t think you’re going to use it and the vast majority of View deployments I’ve seen use Composer, so I didn’t see it as necessary to separate that into a different role either.  You’ll also note that I used the privilege “Id” instead of “Name”.  The problem I ran into there is that “Name” is not unique within privileges (e.g. there is a “Power On” under both “vApp” and “Virtual Machine”) while “Id” is unique.  So, for consistencies sake I just used “Id” to reference every privilege.  The only thing that will need to be modified in these scripts is to make sure to enter your vCenter IP/Hostname after “Connect-VIServer”.

Of course, these scripts could be expanded to automate more tasks, such as creating a user account and giving access to specific folders or clusters, etc., but I will let all the PowerCLI gurus out there handle that. 🙂  Really, the only goal of these scripts is to automate the particular task that most people skip due to its tedious nature.  Feel free to download, critique and expand as necessary.
