Changing a user's sid is a really bad idea, so in the AD DC (at least)
is is made quite difficult.  

In particular, it is critical that it remain unique, and be removed from
the RID pool.  When we do a classicupgrade, we take care to ensure all
RID pools start above the users we import.  That is really the only time
it is safe to force a RID.

Why do you need to change it?
