This is the database-map type used with aliases files, if the hash type is unavailable. This type is also needed on machines that employ NIS because the underlying files for those services are stored in dbm format. Note that because of the implicit limit on the size of a piece of data, you should consider using one of the db(3) hash or btree types instead.
