   You are right that there should not be any changes needed in the map 
file. Make sure that you have built MapServer with OGR support (USE_OGR).
  The SLD seems to be valid from what I can see. From your settings it 
should have the same effect as setting the OPACITY value on the 
geosignal layer to 60. Does setting the opacity value manually in your 
layer and not using the sld gives you the expected result ?
