OK, you can only work with what you have, in an ideal world, you would 
have a spare machine lying around, but this isn't an ideal world :-)

So your users do have a uidNumber

And Domain Users does have a gidNumber, looking good so far :-)

This proves it is a cache problem.

Is it that the user is still getting the wrong uid, or does the home 
directory belong to the wrong uidNumber (this is more likely).

If the home dirs belong to the wrong uidNumbers, then restarting is not 
going to fix this, you are going to have to 'chown' them i.e. 'chown 
marco:Domain\ Users /home/SAITEL/marco'

I certainly wouldn't remove it from a running system, and you may not 
have to remove it, see how you go on.
