Configure RDP Auth on Mac OS X Host

[ericjray]

All,

I'm attempting to configure authentication -- pretty much any kind at this point -- with a Mac OS X
host, VirtualBox, and RDP. (Mountain Lion, specifically.)

VirtualBox 4.2.6. Extension Pack installed.

I'm using the Microsoft RDP client from the same host for testing.

I can connect with NULL authentication and it works fine, but obviously that's not really viable for
anything but basic internal testing.

External authentication (using my auth creds for the Mac host) fails.
Simple authentication (configured per Chapter 7) fails.
Guest authentication (using auth creds from the guest) fails.

When the connection fails, I get the usual uninformative error from RDP:
"You were disconnected from the Windows-based computer. Someone with access to the Windows-based computer
may have ended the connection, or the Windows-based computer has dropped the connection."

I've done a similar configuration on Ubuntu, and it just works.

Any pointers would be appreciated. Following the directions on the Web pages just isn't resulting in happiness here.

Thanks,
Eric

If anyone has a thought on this I would appreciate it. I have gone through the same steps that ericjray did and have had no luck. I can not find any information on how to resolve this and I have spent ten hours digging around trying to find anything useful.

VirtualBox 4.2.10
Mac OS 10.8 Host
Windows XP Guest
Microsoft Remote Desktop Connection and iTap Mobile RDP

Anybody at all have any ideas or experience? This is a show stopper for me if I can't get it working.

If it helps here is the most recent log from the Virtual Machine.

I still really need help on this one. Anybody?
