Log:

a little speed tester for ldb/tdb

I wrote this to see if using a ldb for idmap store (the equivalent of
winbindd_idmap.tdb) makes sense. It's a long lived database that
administrators may wish to edit, so ldb makes sense, but at the moment
ldb is too slow. This test will help us speed it up.
