After some searchs, i found it was a problem with the STATUS 
default/on/off.
The behaviour of default is strange for me because i thought the value 
by default was on and then i was wondering why the layer did not appear 
with the ON value but appeared with the DEFAULT value.
To debug the mapfiles i found it's a good thing to save the mapfile with 
the save function in PHP.
