Then why does the wikipage have these lines:

idmap config * : backend = autorid
idmap config * : range = 1000000-1999999

Wouldn't it work just as well with:

idmap config * : backend = tdb
idmap config * : range = 1000000-1999999

My problem with that is, as far as I am aware, tdb is an allocating 
backend and you cannot ensure that users on each member of the cluster 
will get the same ID.
