RDesktop + Sun Rays = no screensaver before login?

Hi everyone.

We have a Solaris 9 server powering 50 Sun Ray workstations at the high
school where I work. I just recently got the Controlled Access Mode
pushing out an rdesktop connection to our Windows 2003 Terminal Server.
 Everything seems to be working great except for one detail - there is
no screensaver on the terminals before a user logs in.

The root of the problem is simply that the Sun Ray session doesn't get
a chance. After displaying the Windows login window for three minutes
(exactly), the session restarts, does a little reconnect thing with the
unlocked padlock and then bounces back to the Windows login window.
After a user logs in this behaviour stops and the screen is blanked
normally after sitting idle for a while.

Is this an rdesktop or Sun Ray thing? Is it a Windows 2003 Terminal
Server timeout limit that I've missed? I have no idea but I'd like to
get this figured out before our Sun Rays burn-in the ghostly figure of
a login box to their monitors. ;)

A bit more about our environment:
Terminal server:
Windows 2003 SP1, Novell Client 4.91 SP1 installed
Per-Device Licensing

Sun Ray server powering 50 Sun Ray devices:
Solaris 9 running Sun Ray Server Software 3.0
CAM installed and configured for 60 users

Wrapper script running rdesktop:
---------------
#!/bin/sh

/usr/local/bin/rdesktop -f -k en-us -N -a 16 -5 -n $USER -r sound:local
<IP of Terminal Server>
---------------

(The reason I used a script rather than entering the rdesktop command
directly was the Sun Ray Server Software kept removing the $USER
variable from kiosk.conf, which makes the hostname unique for each Sun
Ray's connection to the Windows terminal server.)

Any input and suggestions are welcome. Thank you for your time.
