Did you conigure db_enum in any special way?
Or, ok, did you configure db_enum at all?
I see that if I don't touch it on my local system, it only list cached and
builtin accounts.
But if I set "db_enum: all", I get all local SAM accounts as well as a
duplicated entry from cache. (No "files" on local system, so…)
