Hi Ferencik,
Your map file appears to be missing a legend object, Its a block
similiar to the layer objects or web, reference, scalebar objects but
it sets up the layer including telling mapserver the name and location
of your legend template file, and whether the legend is On, Off, or
Embedded.
Within the mapfile documentation, the Legend object is described here:
http://mapserver.gis.umn.edu/doc44/mapfile-reference.html#legend
I use CGI mapserver, with HTML templates, using the [legend] tag, with
no need to set any 'mode=legend' value anywhere. The legend object of
the mapfile tells mapserver to process it when the map / scalebar /
reference image are generated.
Cheers,
Ken Lord
