Ok, I looked back at what do currently context contain in passdb (see
below Appendix A).
It is simply a structure containing the function pointers of the
Of course it need to stay here, it only have a really bad name that make
you think of a totally different thing :-)
I think pdb_functions could have been a better name (no not methods, we
are programmin in C not in Java ;-)
typedef struct pdb_context
struct pdb_methods *pdb_methods;
struct pdb_methods *pwent_methods;
/* These functions are wrappers for the functions listed above.
They may do extra things like re-reading a SAM_ACCOUNT on update */
BOOL (*pdb_setsampwent)(struct pdb_context *, BOOL update);
void (*pdb_endsampwent)(struct pdb_context *);
BOOL (*pdb_getsampwent)(struct pdb_context *, SAM_ACCOUNT *user);
BOOL (*pdb_getsampwnam)(struct pdb_context *, SAM_ACCOUNT *sam_acct,
const char *username);
BOOL (*pdb_getsampwsid)(struct pdb_context *, SAM_ACCOUNT *sam_acct,
const DOM_SID *sid);
BOOL (*pdb_add_sam_account)(struct pdb_context *, SAM_ACCOUNT
BOOL (*pdb_update_sam_account)(struct pdb_context *, SAM_ACCOUNT
BOOL (*pdb_delete_sam_account)(struct pdb_context *, SAM_ACCOUNT
void (*free_fn)(struct pdb_context **);
