No. back-mdb does indexing, the same as back-bdb/hdb. But all of back-mdb's
Index databases are stored in the single data.mdb file.

If you build the mdb_stat program in the libmdb source (it is not built by
default) you can use it to examine the individual MDB databases. E.g.:

mdb_stat /var/lib/ldap/mdb-db objectClass

(Assuming the data is stored in /var/lib/ldap/mdb-db)
