Thanks to all who responded to my original question regarding how to get a
SOlaris 2.x machine to automatically log in as a user at boot time.

Dieter Gobbers (gobbers@faw,uni-ulm.de responded with:
add something like
ru:23:respawn:/usr/appdir/bin/ru <user name>
in /etc/inittab.
But be careful and read the manpages before ;-)
Glenn Satchell (glenn@uniq.com.au) responded with:
What about putting it in a script in /etc/rc3.d/S99ru that does the
same
thing?
Joe Yao (jsdy@cais.com) responded with:
Write a script that sets appropriate envoronment variables, opens
stdin
and stdout and stderr, and does whatever 'init' used to do for
'getty'.
Call this program from inside 'inittab' with an appropriate label and
at
an appropriate level.
I ended up creating the following entry in /etc/inittab which calls the
script that follows.
mp:34:wait:/<path to bin directory>/auto_login >/dev/console
2<>/dev/console </dev/console
Auto_login script:
#!/bin/csh
# @(#)auto_login.csh 1.1 97/12/08 (c) Copyright 1997 RSA
set HOME = <path to users home directory>
set USER = <user name>
# Verify that our user exists.
set exists = `ypmatch $USER passwd >& /dev/null`
if ( "$exists" == "" ) then
set exists = `grep "^^$USER" /etc/passwd`
if ( "$exists" == "" ) then
echo "Could not locate $user in either the NIS passwd map or"
echo "/etc/passwd. Without this user, the SW loaded"
echo "in ${HOME} cannot run."
echo "Please check that the installation completed successfully."
exit 1
endif
endif
# see if dtlogin session is already running - if so stop it
set dtrunning = `ps -eaf | grep dtlogin | grep -v grep | head -1 | awk '{
print $2 }'`
if ( "$dtrunning" != "" ) then
/etc/init.d/dtlogin stop
endif
# The following line changes the ownership and mode of files (like /dev/fbs
# and /dev/kbd) that OpenWindows uses. By default, these files have a
# permission of 0600 and are owned by root. Normally, login(1) sets these
# permissions and modes however... as usual we are not normal. This is
# necessary for OpenWindows to run for a non-root user.
#
/usr/bin/chown $USER /dev/console /dev/kbd /dev/fbs/* /dev/sound/*
/dev/mouse >& /dev/null
# Now launch OpenWindows as the non-root user
# Note that this will cause the error message "can't access tty - no job
control for
# this shell" when the program runs. This is normal and will not cause any
problems
# with running the system.
su - $USER
# Done.
