@matthieu-jacquart Sorry I can only write in english.
Its best if you DO NOT connect your mother/master image to active directory before you capture the image. I’m sure my environment is different than you, but we use MDT to create the golden image, sysprep then capture with FOG. At no time is the golden image connected to AD before capture with FOG. The first time the target computer image is connected to AD is on the final hardware.
