Taking your example 'idmap config DOMAIN : range = 100000-199999' it is 
very easy, you just need users whose RIDs are larger than 200000, these 
users will be ignored.

Something similar was problem wrong with the 'ad' backend when you tried 
it, failing that it was probably a lack of 'uidNumber' & 'gidNumber' in AD.

As Marc has pointed out, with the 'rid' backend you do not get to set 
home dirs & shells on a per user basis.
