Public bug reported:
When I login from a thin client, I get this message directly on the server
console (also after plugin in a device):
X11 connection rejected because of wrong authentication.
I think it's from the /usr/share/ldm/rc.d/S10-delayed-mounter script.
Following the steps on DebugLocalDev, all is correct until the last
step.
----
Step 1: Is the device partitioned?
Yes
Step 2: Is ltspfs installed on the server?
Yes

Yes

I've tried both with Ubuntu server and Edubuntu (Gutsy), but neither works.
Although
with Edubuntu I'd to run ltsp-build-client manually because of bug #159526.
The only thing I do after the installation is modify /etc/network/interfaces,
disable dhcpd (it's in another server) and run ltsp-build-client,
ltsp-update-sshkeys and ltsp-update-image.
