624.0. "Auto loggin " by SWAM1::POIANI_MI () Thu Mar 20 1997 12:12

    I have a customer running Digital UNix 3.2G with CDE turned on. They
    would like to have digital UNIX automatically log them in when they
    reboot. 
    
    They will also be upgrading to 4.0b with CDE so this should work for
    both, and yes they are aware of the major security problems with this
    as they want to login as root. They are using a locked door for
    security and the machine is not on the net.

	For some background reading, take a look at the response in 6937.5
	in this conference. That explained how to do it for a V3.2 
	DECwindows environment.

	The approach for CDE is similar - replace the startup/stop
	scripts in /sbin/rc3.d with customized versions. The problem is
	that CDE rather heavily depends upon cleanly coming through 
	the dtlogin process to set up environment variables, so that
	more work is needed.

	I've played around with this on a V4.0 system - I no longer have
	easy access to a V3.2 system. This appears to work for the most
	part. It could use some cleanup, and should be made to do something
	more clever if the user logs out of CDE, but it's a proof of
	concept.

	Rename the existing /sbin/rc3.d/S95xlogin script on a V4.0x system
	and create another script (e.g., S95noxlogin) with the following:

#!/bin/sh
DISPLAY=war.unx.dec.com:0.0         # replace with your system name
export DISPLAY
