The next lines are for those who cannot configure their XDMCP hosts.

1st - you better use gdm instead of xdm. But if you still want xdm
     (less memory footprint and much more faster but hard to configure)
      here what you should do.

1. Locate your xdm conf. directory
   (xdm location in slackware 7.1 is /usr/X11/lib/X11/xdm)
2. If you don't want to run any X server on that host and login ONLY
   remote by XDMCP, edit Xservers file and comment out line like this:
      :0 local /usr/X11R6/bin/X
   to become:
      #:0 local /usr/X11R6/bin/X
3. In order to start XDMCP service you should edit Xaccess file and be sure
   that it has the lines bellow:
      *
      *               CHOOSER BROADCAST
   Note that this is the quick hack. If security is important then
   consult with xdm man pages

Configuring gdm
1. locate gdm config file directory
   (location in slackware 7.1 is /usr/X11/lib/X11/gdm
2. Edit gdm.conf file and be sure that there is xdmcp is enabled in xdmcp section:
    [xdmcp]
    Enable=D1
3. Notice that
    [security]
    AllowRoot=0
   Will still allow root to login in gdm v 2.0beta4.
   There is a dirty hack i did:
   Locate Xsession file for gdm and put these lines:
    if [[ $USER = root ]]; then
      exit
    fi
