[arch-general] Arch Linux PC as a Remote Desktop Node

[Foxtrot Mike]

Hi all,

Currently we have around 10 employees who develop software using Visual 
Studio. The idea is to install the development tools on the Windows 
Server system, and to have all the developers connect to the server over 
RDP using low-end low-power computers. The server is pretty beefy 
though. The low end client PCs will save up-front cost as well as power 
bills. The network backend will not have any issue with the increased 
RDP traffic.

I have been using Arch Linux for some years now, so I undertook this as 
a research project. I  want to use the Arch system as a Remote Desktop 
node. The Arch system would use a login manager (such as lightdm) to 
authenticate users from Windows Domain. Once the user has been 
authenticated, the system is supposed to automatically open a RDP 
connection (using freerdp) to the Windows Server (if possible, using the 
credentials provided to lightdm so the user doesn't have to enter his 
password twice). As soon as the user quits the RDP session, his 
X-session should also be closed automatically.

Here are the major tasks:

1- Ask LightDM to use Windows Domain (Kerberos) authentication. I am a 
little confused. There are supposedly many different ways with little 
changes to do this. [1] is one solution. LDAP is also a possibility. I 
need advice from someone who knows this field better than me :p

2- How to ask i3-wm (my default wm) to run freerdp at login? I guess [2] 
will get this done.

3- How to ask freerdp to authenticate using the ticket received from TGT 
during LightDM Domain authentication? If I could somehow configure 
freerdp to use Kerberos Tickets then the user won't have to enter his 
Domain password again.

4- How to ask i3-wm to close the X-session when freeRDP quits? I read 
something a while ago about .xsession files to achieve this 
functionality, but can't find it now.

Any help would be appreciated!

Regards.
