Can't Detach from a startup script

[Kent West <westk@acu.edu>]

I'm trying to run Maple12 from my Debian box. I've hacked a startup 
script together that looks like this:

<Beginning of Script>
==============
#! /bin/sh

# Maple 12
# I hacked this script from a copy of the "lisa" start-up script; no 
guarantees that it works properly.
# Kent West, 14 June 2007

PATH=/sbin:/bin:/usr/sbin:/usr/bin
DAEMON=/usr/local/Maple_Network_Tools/FLEXlm/lmgrd
OPT=" -c /usr/local/Maple_Network_Tools/activate/Maple12.lic -l 
/var/log/maplelicense"
NAME=lmgrd
PIDFILE=/var/run/$NAME.pid
DESC="Maple License Server"
USER=maple

test -f $DAEMON || exit 0

set -e

case "$1" in
 start)
       echo -n "Starting $DESC: "
       start-stop-daemon -c $USER --start --quiet --pidfile $PIDFILE 
--exec $DAEMON -- $OPT \
               > /dev/null
       echo $(pidof lmgrd) > $PIDFILE
       echo "$NAME."
       ;;
 stop)
       echo -n "Stopping $DESC: "
       start-stop-daemon --stop --quiet --oknodo --pidfile $PIDFILE \
               --exec $DAEMON
       rm -f $PIDFILE
       echo "$NAME."
       ;;
 reload|force-reload)
       echo "Reloading $DESC configuration files."
       start-stop-daemon --stop --quiet --signal 1 --pidfile $PIDFILE \
               --exec $DAEMON
       ;;
 restart)
       echo -n "Restarting $DESC: "
       start-stop-daemon --stop --quiet --oknodo --pidfile $PIDFILE \
               --exec $DAEMON
       rm -f $PIDFILE
       sleep 1
       start-stop-daemon -c $USER --start --quiet --pidfile $PIDFILE 
--exec $DAEMON -- $OPT \
               > /dev/null
       echo $(pidof lmgrd) > $PIDFILE
       echo "$NAME."
       ;;
 *)
       N=/etc/init.d/$NAME
       echo "Usage: $N {start|stop|restart|reload|force-reload}" >&2
       exit 1
       ;;
esac

exit 0

============
</End of Script>

Tonight I added in the "-c $USER" piece under the "start" and "restart" 
stanzas, because otherwise the deamon was running as root, which is not 
recommended by makers of Maple. (I created a user named "maple" and set 
the shell to /bin/false; anything else I should do to tighten the 
security on that user?)

Before I made this change, I could ssh into the box, run "sudo 
/etc/init.d/maplelicense start", and then exit from my ssh session.

Now when I run the script, my ssh session won't let go; it just hangs 
after I type "exit". If I ssh in from another shell and run "sudo 
/etc/init.d/maplelicense stop", my first ssh session then terminates.

I see from the start-stop-daemon man page that I might can throw in a 
"-b" to force a detachment, but is that the correct way to fix my 
problem? The man page suggests that this should be a last resort.

Thanks!
