User 1, who belongs to groups A and B, logs on. Because Role 2 is assigned at a lower point in the
hierarchy than Role 1, it overrides Role 1 on VM B. User 1 can power on VM A, but not take snapshots.
User 1 can take snapshots of VM B, but not power it on.

Example 3: User Role Overriding Group Role
This example illustrates how the role assigned directly to an individual user overrides the privileges
associated with a role assigned to a group.
In this example, permissions are defined on the same object. One permission associates a group with a
role, the other permission associates an individual user with a role. The user is a member of the group.

Role 1 can power on virtual machines.

Group A is granted Role 1 on VM Folder.
n
User 1 is granted No Access role on VM Folder.
User 1, who belongs to group A, logs on. The No Access role granted to User 1 on VM Folder overrides
the role assigned to the group. User 1 has no access to VM Folder or VMs A and B.

Managing Permissions for vCenter Components
A permission is set on an object in the vCenter object hierarchy. Each permission associates the object
with a group or user and the group's or user's access roles. For example, you can select a virtual machine
object, add one permission that gives the ReadOnly role to Group 1, and add a second permission that
gives the Administrator role to User 2.
By assigning a different role to a group of users on different objects, you control the tasks that those users
can perform in your vSphere environment. For example, to allow a group to configure memory for the
host, select that host and add a permission that grants a role to that group that includes the
Host.Configuration.Memory Configuration privilege.
