[OpenLayers-Users] [newbie] Different projections, Mapserver as WMS

[Julien-Samuel Lacroix]

Hi,

Your MapServer layer probably doesn't support the EPSG:4326 projection. 
To make it support this projection, you must specify it in the wms_srs 
metadata in your mapfile.

This metadata list all SRS available for the layer. See the wms_srs 
metadata explanation here:
