Windows RDC client under OSX fails to connect to VRDP with auth.

[husk]

I've set up VirtualBox 3.1.4 on a XP box (host) then installed a CentOS 5.3 (client) and when trying to connect to the host using port 5050 (external authentication) using Microsoft RDC 2.01 (OSX) I keep getting "You were disconnected from the Windows-based computer". I can connect using local Microsoft desktop connection on the XP host by specifying user name and password.

From the logs:

Running mstsc from host directly I was connected

It appears to me that Virtualbox VRDP does not handle the "domain" info correctly that is being sent by Microsoft Remote Desktop 2.01 for OSX. IE it does not parse out the domain info.

I just downloaded 3.2.4 and VRDP with external authentication seems to work :-)

Following is from log:

......

00:03:35.243 VRDPAUTH: external authentication module returned 'access granted'

......

I did notice that when logging into the XP box using 3389 as opposed to 5050 (5050 is the VirtualBox port) the Virtualbox screen is full screen but it is easy enough to resize.

I believe this is fixed

Thanks for the feedback.
