You can still configure connections locally even if the administrator override file is set. You can enable administrator override in the Rumba APPC Configuration tool and still create link configurations that you store on the workstation in a local configuration file. However, there are restrictions. You are able to configure local connections only when they have a different connection name and remote LU alias from any other link residing in the administrator override file. See Configuration files precedence.
Also, similar to document printing, the AS/400 display shows only connections configured in the administrator override file, and users can only connect to these administrator override configured connections.
