Remote Display using External Authentication
Posted: 17. Dec 2017, 22:17
Because my VM is publicly accessible, I would like to setup authenticated remote access and according to the manual (https://www.virtualbox.org/manual/ch07.html#idm3499):
On Mac OS X hosts, VBoxAuth.dylib authenticates users against the host's directory service.
In other words, the "external" method per default performs authentication with the user accounts that exist on the host system. Any user with valid authentication credentials is accepted, i.e. the username does not have to correspond to the user running the VM.
I am able to successfully use "null", but as the manual states,
The "null" method means that there is no authentication at all; any client can connect to the VRDP server and thus the virtual machine. This is, of course, very insecure and only to be recommended for private networks.
As soon as I change the Remote Display > Authentication Method from Null to External, I am no longer able to connect using the latest version of Microsoft Remote Desktop. The screen shows "Connecting RDP..." and the screen disappears with no error.
Any ideas on how to get this working would be greatly appreciated.
