.NET UI Security
The .NET UI supports external customized menus defined in XML. The ability to customize menus allows you to add content—the QXtend plug-in, for example—outside of standard programs and functions.
The items on external menus are not filtered unless a security constraint is added to the menu; this is achieved by manually editing the menu extension configuration file. Security constraints can be placed on the XML file by user or role.
For details, refer to the installation guide.
