Hey Guys,

First a little introduction: My Institute is integrated into the university's domain system with Kerberos authentication. I wanted to create a laboratory computer to which everybody has to log into with one's domain account but still has the same desktop an system for measuring. I therefore integrated the host XP into the domain and installed VirtualBox headless and as service with WinXP. That works totally fine so far. My idea was then to log into the VM over VRDP. An here is the problem - It seems, that the RDP integration is not fully compatible with Windows RDP as external authentication is only working with preset accounts and password and local resources like local hard drives aren't connected to the remote machine.
Unfortunately shared folders are not helping as the machine is running as a lokal service that hast no access to mapped network drives domain users have access to.
Is there any way to get the network drives of users logged into the host system work in virtualbox?

Thank you so far,
Christian Kirsch

Btw: Great program! VirtualBox is running so much better on older machines than VMWare or VirtualPC

Yes use RDP not vRDP.

I already tried this, but then there is no way of authenticating against the Kerberos domain as the client system should not be in the domain.

Are you trying to pass on/use authentication for the Guest via the Host? if so radius would do nicely. Ea. use a radius server on the Host that authenticates via Kerberos where a Guest becomes a client.

Hi,

I'm not sure if I understood you. Right now I could log into my vm with windows rpd and set up the local resources. The only problem with that is, that rdp (not vrdp) authentication is only possible against the vm's users. So I need to set up a local user and give everybody the password, but I don't like that.
So how could a radius-server help me then?

Make Radius act as a secondary layer, use one single user on the Guest. You're gonna need some kind of layer to authenticate a none related VM to an external source, the only way to do this is by way of a 2 pass system whereby the Host acts as a 'routing' agent. Radius is capable to do that, how exactly is beyond the scope of this forum.
