Right. I was trying to give my owm sightly more substantial
version of Jeremy's idea, which really has its appeal.
But Mathias has already given a good example
when this will be wrong for someone: If you use
SFU via idmap_ad - In this case the IDs are not
under the samba admin's control, and we may not
have a chance to stay above IDMAP_LOW.
Thinking about it, we could introduce an extension
of idmap_ad to circumvent it: we could add some kind
of offset or shift parameter to idmap_ad, which
specifies a minimum number to which the xids
from SFU are added. Not precisely beautiful
but would allow one to have the IDMAP_LOW barrier... :-)

Yeah, I also think we need a way out...
