Thanks for your response.
In our frontend we use the following projection string for EPSG:28992:
+proj=3Dsterea +lat_0=3D52.15616055555555 +lon_0=3D5.38763888888889
+k=3D0.9999079 +x_0=3D155000 +y_0=3D463000 +ellps=3Dbessel
+towgs84=3D565.417,50.3319,465.552,-0.398957,0.343988,-1.8774,4.0725
+units=3Dm +no_defs
I hope these parts of the map file are informative enough:
