Comment by Rishi for If properly configured, there is no form showing up. All you need is to provide proper admin credentials when installing FreeRDP-WebConnect. Horizon will take care of the console authentication, passing a token to FreeRDP-WebConnect that will be used by wsgate to query your Nova environment for the Hyper-V host and VM id.

Thanks for your reply. However I am not using openstack or horizon for authentication. Instead looking for some API to open the console in iframe or similar on my custom portal.
