No access nodes
A no access node represents a system object that you can see in a BMC Server Automation Console but you cannot interact with because you do not have the appropriate authorizations.
BMC Server Automation uses italics to distinguish no access nodes from system objects for which you have permissions. Using preferences you can specify whether a BMC Server Automation Console displays no access nodes (see Customizing preferences).
The RBAC Manager folder never shows no access nodes. In that folder, if you are not authorized to read a system object, you cannot see the object.
Although you may be able to see a no access node, if it represents a hierarchical object, you cannot see any of the object's children. For example, you can see a no access server group, but you cannot see any servers in that group.
