I take it you are referring to ID numbers in the '3000000' range on the
DC. If so, these are NOT uidNumber or gidNumber attributes, they are
xidNumber attributes and are only used on a DC (and unless you sync
idmap.ldb between DCs, only that DC). If you do add uidNumber &
gidNumber attributes to AD these will be used instead of the xidNumber
attributes.

Well it would be, if you could use the 'idmap.config' lines on a DC,
but you cannot, they do not do anything.
