And idmap_autorid is broken by design, it only gets you the ID's,
nothing else.
I personally think that what is required is something like a cross
between the 'ad' backend and everything else.
The 'ad' backend to set homedirs, login shells etc and everything else
to set the ID's from the RID, the domain could be identified from the
SID.
