If any of your XDM manager hosts are running X11R3, you can configure them as described in "Configuring XDM Hosts" with the following additional steps:

1. Place an entry for each terminal in the Xservers file. Entries in this file have the following syntax:
   

   
   hostname:0 foreign comment
   

   
   where hostname is the IP address or hostname of the terminal and comment is any word. For example:
   

   
   ncdu10:0 foreign magic-cookie
   

2. Make sure login is not included in the exec-startup-commands table (Setup -> Change Setup Parameters -> Commands and Startup -> Startup Commands).
