Correct.  xdm on the server needs to be configured to listen for XDMCP. 
On my systems this is done by commenting out the 
DisplayManager.requestPort line in /etc/X11/xdm/xdm-config like this:

!DisplayManager.requestPort:    0

Then restart xdm.  Of course, this assumes that you use xdm to manage X 
logins.  You may be using gdm or KDE's equivalent (kdm?).

The problem may also manifest itself when using ssh, but I haven't tested 
that.  Using ssh would clearly be the way to go over an untrusted network, 
but over the LAN we simply use XDMCP.

if you want to understand why that is, there are many good books on
the design of operating systems. please pass them along to redmond
when you're done reading them :)
