Samba4 Port: hdb & ldb Interfaces

This page aims to reduce the confusion about the two hdb interfaces, the LDB interface, and the big ldb interface.

LDB Interface

source4/kdc/hdb-samba4.c contains the LDB functions. In Samba4's heimdal/lib/hdb/hdb.h, Heimdal's HDB structure contains "hdb-" prefixed function-pointers to the LDB functions:

(HDB *)->hdb_dbc = NULL;
(HDB *)->hdb_open = LDB_open;
(HDB *)->hdb_close = LDB_close;
(HDB *)->hdb_fetch = LDB_fetch;
(HDB *)->hdb_store = LDB_store;
(HDB *)->hdb_remove = LDB_remove;
(HDB *)->hdb_firstkey = LDB_firstkey;
(HDB *)->hdb_nextkey = LDB_nextkey;
(HDB *)->hdb_lock = LDB_lock;
(HDB *)->hdb_unlock = LDB_unlock;
(HDB *)->hdb_rename = LDB_rename;
(HDB *)->hdb__get = NULL;
(HDB *)->hdb__put = NULL;
(HDB *)->hdb__del = NULL;
(HDB *)->hdb_destroy = LDB_destroy;

hdb Interface

Samba4's heimdal/lib/hdb/hdb.c defines another set of hdb_ functions:

hdb_next_enctype2key
hdb_enctype2key
hdb_free_key
hdb_lock
hdb_unlock
hdb_free_entry
hdb_foreach
hdb_check_db_format
hdb_init_db
hdb_list_builtin
hdb_create
