>Here is a short cut-out from the README_INSTALL where you can see my
version-numbers:
 
- Apache version 2.0.55

- PHP version 4.4.3-dev

- MapServer 4.8.3 CGI and MapScript (CSharp, Java, PHP, 
  Python)
  
    - support GD 2.0.33, FreeType 2.1.10, GDAL/OGR 1.3.2, 
      PROJ, WMS/WFS, Flash, PDF, ECW3.1, PostGIS, GEOS, 
      libcurl 7.15.0  
    
- mapserver utilities

- gdal/ogr utilities

- proj.4 utilities

- shp2tile utility

- shapelib utilities

- shpdiff utility
    
- PHP_OGR Extension 1.1.1
    
- OWTChart 1.2.0

I have not installed some of them separat so that are the versions I'm
using.

I tried out your idea to use CONFIG "OGR_FID" "name_of_your_primary_key",
but the result is still the same. I think posting the newest Mapfile can
never be bad:
MAP
	NAME WFS_Server
	STATUS ON
	WEB
		METADATA
			"wfs_title"            "WFS Server" 
			"wfs_onlineresource"   "http://127.0.0.1/cgi-bin/mapserv.exe?"
			"wfs_srs"               "EPSG:4326"
		END
	END

	PROJECTION
		"init=EPSG:4326"
	END

	CONFIG "OGR_FID" "id"
	
	LAYER
		NAME myWFS
		METADATA
			"wfs_title"    "myWFS"
			"gml_include_items" "all"
			
		END
		TYPE POINT
		STATUS ON
		CONNECTIONTYPE OGR
		CONNECTION "test.ovf"
		PROJECTION
			"init=EPSG:4326"
		END
		DUMP TRUE

	END
END


Best Regards
Christian
