The menu items displayed in the administration menu depend upon the actual permissions of the viewer. First, the administration menu is only displayed to users in roles with the <em>Access administration menu</em> (admin_menu module) permission. Second, a user must be a member of a role with the <em>Access administration pages</em> (system module) permission to view administrative links. And, third, only currently permitted links are displayed; for example, if a user is not a member of a role with the permissions <em>Administer permissions</em> (user module) and <em>Administer users</em> (user module), the <em>User management</em> menu item is not displayed.
