[foxboro] What Generates the "No Licenses" error meesage for Remote Display Manager?

WE have a node with only a couple of Remote Display Manager Licenses on it,
and we have a problem with people forgeting to log off of it. We have even
found instnaces where 1 user would have iconofied one copy & started
another ;_(

So, I modifed the .profile for the ia user (/opt/is/.profile) to look like
this:


--------
PATH=/bin:/usr/bin:/usr/sbin:/etc:/usr/ucb:/usr/local:/usr/ccs/bin:.:/usr/opt/SUNWmd/sbin:/opt/gms/bin:/usr/fox/wp/bin/tools
export PATH

# Need to set up library path for jettool (needs libview.so.x)
# LD_LIBRARY_PATH=/usr/openwin/lib ; export LD_LIBRARY_PATH
LD_LIBRARY_PATH=/opt/gms/lib:/usr/openwin/lib:/usr/dt/lib:/opt/windu/lib:/opt/windu/fox
 ; export LD_LIBRARY_PATH
l () ls -l $*
lc () ls -CF $*

#
# Added "-sig" arg to blink_task to avoid the Display Manager starting
# up before blink_task is fully initialized.  blink_task uses SIGUSR1
# to signal back.  This signal is different between the platforms.
# So we need to determine what signal to trap on
#
SIG_PATH=/usr/include/sys/signal.h
SIGUSR1=`grep SIGUSR1 $SIG_PATH | awk '{ printf ( "%s", $3 ) }'`

REM_STATION=`who am i| awk '{print $6}' | tr -d "()"`
LOC_STATION=`uname -n`

DISPLAY=$REM_STATION:0 ; export DISPLAY
echo Setting DISPLAY to $DISPLAY

WUHOME=/opt/windu ; export WUHOME
GMS_HOME=/opt/gms ; export GMS_HOME
HHPATH=/opt/windu/bin ; export HHPATH
HHHOME=/opt/windu ; export HHHOME

# The next 2 lines record the time at which this 
# dm session will be auto terminated.
# To change the time before termination modify the echo line,
# changing the value between the ' ' after --date= 

LIMIT_FILE=limit_file$REM_STATION
echo `/opt/gnu/bin/gdate --date='1 hour' +%s` > $LIMIT_FILE

if [ -z "$REM_STATION" -o "$REM_STATION" = "$LOC_STATION" ]
then
   exit
fi

#

if [ -s $HLDB ]
then
   TYPE=`awk '{   if ($1 == "'$LOC_STATION'")
                  {
                     # filter out non-WP/AW stations
                     # WP/AWs station types:

                     if ( $2 ~ /[234]0[0-9]/ )
                     {
                        print $2
                     }
                     exit
                  }
              }' $HLDB`

-------------

This limits a givne session to 1 hour. This works well, and does exactly
what we want, _except_ for one minor problem. If someone atempts to log in,
and there are no licenses available, the normal blue error dialog for this
_does not_ pop up. This confises the users.


The only difference that strikes me, is that I am disposing default_dm to
the background, but I can't see how this should prevent it from generating
the error dialog.

What am I missing?
