They should all be very similar, the difference is that the xidNumber
attributes are set on a first come basis, this means that a user or
group gets the next xidNumber available and you cannot guarantee the
order that they contact the DC, so 'Domain Users' (for instance) may
have a different ID on each DC

Doubtful, can I try and get across that idmap.ldb has nothing to do with
your missing line, without the line, a DC will only use the xidNumber
attributes in idmap.ldb
This means that all the idmap.ldb files are viable, they are just likely
to have different ID's for users & groups.

Only if you like doing work that is pointless.
