[gdm-list] redirecting connection from remote host

[Ashish Khurange <ashishk it iitb ac in>]

Hello,

I'm developing a High availability cluster for thin clients. For this I 
have following requirements.

1. There is a master server, which is used by thin clients to get the 
kernel code and boot. It is also the load balancer in the system.
2. All the thin clients after booting sends a xdmcp direct query to load 
balancer.
3. Load balancer will provide login screen to thin clients, get thin 
clients authenticated.

Up to this part everything is OK.

4. After the authentication, the load balancer has to take scheduling 
decision depending on user authenticated, load on various servers.
5. The load balancer will select an optimal server to serve this user.
6. Now the connection of thin client with load balancer should be broken 
and the thin client should establish new connection with the selected 
server.
7. The selected server should provide auto-login to the user, it should 
not ask for login again. That is this redirection should be transparent.

I don't have much information about GDM & XDMCP. So, is it possible to 
do this? If yes, which part of code of GDM I need to dig? Also please 
tell me how to get started to understand the code of GDM.

Thank you all in advance.
