Currently in version 11.08.440 you can set the “Default Domain”, however this still shows a selection box if more than 1 domain is configured in Imprivata Appliance (and users are part of it - CS0052644). In some scenarios it would be beneficial to be able to set the Default Domain and lock it so the selection is not available. This will prevent issues when users attempt to login and the domain is set to the wrong one.
