When using RunAs from within the context menu (Shift + Right Mouse Button) of windows for an application, this is not started with the supplied username and password.
This issue only occurs when the installed version is Ivanti Workspace Control 10.2.0.x or higher.
This issue is under investigation by Ivanti Support.
Create an application with the command line runas.exe from the windows installation folder and use the parameter field to supply the /user:domain\user + command line.
The password needs to be supplied upon launch of the application.
