Ha! Forgot a crucial part of the whole story:
"Note here that you need to put a <Name>class1</Name> inside the Rule
element so that a class name is created from the SLD and therefore a
correct legend image." (wms server howto)
Cheers, Michael

Hi,
yes, mapserver will use the sld also for the legendgraphic. It is
however important that you have a class name defined for the layer to
return a legendgraphic. Some minimal legend configuration should also be
present in the mapfile.

Hi List,
Is it possible to make a getLegendGraphic request, using a SLD to define
the style?
I'm using the same SLD in a getMap request, which styles the layers
appropriately, as I am for a getLegendGraphic request, which shows
nothing. If I don't use the SLD, or use a different value in the <Name>
element of <NamedLayer>, the default style is shown in the
LegendGraphic.
I'm only just starrting to look at mapserver, so I might be missing
something simple.
This is the request I'm using:
http://myserver/cgi-bin/mapserv.exe?map=/ms4w/apps/layers/service/sample
_collection.map&service=WMS&REQUEST=GetLegendGraphic&VERSION=1.0.0&FORMA
T=image/png&WIDTH=50&HEIGHT=50&LAYER=Humpback_whale_migration&SLD=http:/
/myserver/test.sld
The SLD:
<?xml version="1.0" encoding="UTF-8"?>
<StyledLayerDescriptor version="1.0.0"

I'd appreciate any help anyone can offer, thanks.
