[K12OSN] Teacher access to teacher tool

[Dan Visentin]

OK... teachers still cannot control, broadcast, etc.  
Error is "Opening password file failed"

Here's what I have done:

created a "teachers" group and made all teachers members
logged in as root
ran vncpasswd
changed password
executed #cp -R -p /root/.vnc /opt/ltsp/i386/root/  (folder is present etc)
ran visudo
added line "%teachers  ALL=NOPASSWD:/usr/sbin/fl_teachertool"
made sure X4_MODULE_02 = vnc was uncommented in lts.conf

teachers still cannot control, broadcast, etc. same error

As a shot in the dark, I tried the following:
made the following changes in build_x4_cfg to reflect recommendations on
fl_teachertool website:

#if [ "$VNC_MODULE_LOADED" ]; then
#   echo '           Option "httpdir" "/usr/share/vnc/classes"'
#   echo '           Option "PasswordFile" "/root/.vnc/passwd"'
#   echo '           Option "rfbport" "5900"'
#   echo '           Option "usevnc"'
#fi

# commented out if statement above to try fl-teacher website config
#=========================================
# Added to enable Monitor/Control in Fl_TeacherTool
   Option "httpdir" "/usr/share/vnc/classes"
   Option "PasswordFile" "/root/.vnc/passwd"
   Option "rfbport" "5900"
   Option "usevnc"
#=========================================

Still same error

I even tried to give the teachers group permissions to read/write /opt/ltsp/i386/root/.vnc folder and passwd file.  This resulted in a new error "no password configured for VNC Auth".

Suggestions?
