Disabling XDMCP

	Tru64 gurus,

I am running 4.0f with Enhanced Security and cde as my login manager.  The security people here are requiring me to disable XDMCP.  Here is what I have tried so far

  1. Adding the resource to /usr/var/X11/xdm/xdm-config: 
DisplayManager.requestPort:     0

  2. Adding the entry to /usr/var/X11/xdm/Xaccess:
!*

  3. Modifying the line in /sbin/init.d/xlogin:
$X_DISPLAY_MANAGER -daemon -udpPort 0 $CONFIG_OPTION

The first two options didn't change the XDMCP behavior.  The last option didn't allow DHCP access which I need.

I don't believe the first two options did anything because there is no xdm process running and there is no xdm-errors or xdm-pid file created.

When the remote host makes an XDMCP Query request, the remote sees a popup dialog:
"Cannot obtain database information on this terminal"
And then a popup with the /etc/issue contents, but no login window.  When the remote host makes an XDMCP Broadcast the remote host gets a Chooser box which includes the Tru64 hostname and then the above two popups.

How can I eliminate any vestige of an XDMCP server?

Many thanks for any insights.
