MapProxy does not load WMS from MapServer 7.0

[kalxas]

When launching MapProxy demo with MapServer as backend, there is an error message: "no image returned from source WMS..."

With rest of the backends, MapProxy works fine.

Full error message:

<ServiceExceptionReport version="1.1.1"><ServiceException>
msWMSDispatch(): WMS server error. WMS request not enabled. Check wms/ows_enable_request settings.
</ServiceException></ServiceExceptionReport>

The following is missing from the itasca.map definition:

WMS_ENABLE_REQUEST "*"

so WMS is not enabled in the MapServer demo.

After manually enabling WMS:

The mapfile is missing a projection block, which is default projection to use for a layer that has no projection defined.

MAP
 ...
 PROJECTION
  "+init=epsg:4326"
 END
 ...
END

Thanks Thomas, The itasca.map file has this part commented out.

  #
  # Projection definition, consult the PROJ.4 documentation for parameter discussion
  #
  # PROJECTION
  #   "proj=utm"
  #   "ellps=GRS80"
  #   "zone=15"
  #   "north"
  #   "no_defs"
  #
  #   OR:
  #
  #   "init=epsg:26915"
  # END

I am going to patch the map file for now, but I think this has to be fixed upstream.
