XRDP v 0.8 and problems with access from Mac OS X 10.9.4 - negotiating credentials fails

david@gradwell.com
I have built a clean build of Debian 7.5 (Wheezy) and installed XRDP 0.8 using x11rdp-o-matic (See URL:  http://scarygliders.net/x11rdp-o-matic-information/).  This works fine (including copy & paste) when accessed from both Windows 7.1 using the Microsoft RDP client and from Windows 8.1.

However when connecting from Apple Mac OS X 10.9.4 using Microsoft Remote Desktop Version 8.0.8 (Build 25010) I get a black screen showing "Negotiating Credentials" for about 1 second after which the connection terminates.

The MRD log is:
[2014-Jul-31 11:09:51] RDP (0): ----- BEGIN ACTIVE CONNECTION -----
[2014-Jul-31 11:09:51] RDP (0): client version: 8.0.25010

[2014-Jul-31 11:09:51] RDP (0): Protocol state changed to: ProtocolNegotiatingCredentials(2)
[2014-Jul-31 11:09:52] RDP (0): Disconnect initiated by server
[2014-Jul-31 11:09:52] RDP (0): Protocol state changed to: ProtocolInactive(4)
[2014-Jul-31 11:09:52] RDP (0): Protocol state changed to: ProtocolDisconnected(8)
[2014-Jul-31 11:09:52] RDP (0): ------ END ACTIVE CONNECTION ------

This seems to be a problem affecting a number of people.  See http://social.technet.microsoft.com/Forums/windowsserver/en-US/4b0624d7-0b6e-4967-b07c-ada1c9f5a772/failure-negotiating-credentials-from-macosx-for-remotedesktop?forum=winRDc 

Happy to investigate further if anyone can guide me.

The Itap MS client set the autologin flag all the time.  Even when you
don't provide a password.  It looks like a bug to me.
I think we did a workaround to only login if the flag is set and the
password is supplied in v0.8.
Can you try with no password and also try with the right username and password?

Thanks
Jay

Re: [Xrdp-devel] XRDP v 0.8 and problems with access from Mac OS X 10.9.4 - negotiating credentials fails

I get the same result (1 second flash up of "Negotiating credentials" followed by the Microsoft Remote Desktop session window closing) when I submit a valid user name and password.

Version 0.5 worked OK from Mac OS X before I installed 0.8.

I can log in successfully from a Windows 7 machine and from a WIndows 8 machine, both using X11-VNC.  X11-rdp gives an "Ooops there is a problem" screen.

What diagnostics should I be looking at ?

I would really like to get rdp to work !

Hi David,

I think i fixed that issue in devel branch, its regarding to a change they did in the last mac rdc client

Can you try and cherry pick that commit form devel branch:

Good day,
