pam_set_item(3pam)
pam_set_item(3PAM) PAM Library Functions pam_set_item(3PAM)
NAME
pam_set_item, pam_get_item - authentication information routines for
PAM
SYNOPSIS
cc [ flag ... ] file ... -lpam [ library ... ]
#include <security/pam_appl.h>
int pam_set_item(pam_handle_t *pamh, int item_type,
const void *item);
int pam_get_item(const pam_handle_t *pamh, int item_type,
void **item);
DESCRIPTION
The pam_get_item() and pam_set_item() functions allow applications and
PAM service modules to access and to update PAM information as needed.
The information is specified by item_type, and can be one of the fol‐
lowing:
PAM_AUSER The authenticated user name. Applications that are
trusted to correctly identify the authenticated user
should set this item to the authenticated user name.
See NOTES and pam_unix_cred(7).
PAM_AUTHTOK The user authentication token.
PAM_CONV The pam_conv structure.
PAM_DISPLAY The value of the DISPLAY environment variable.
PAM_OLDAUTHTOK The old user authentication token.
PAM_RESOURCE A semicolon-separated list of key=value pairs that
represent the set of resource controls for applica‐
tion by pam_setcred(3PAM) or pam_open_session(3PAM).
See the individual service module definitions, such
as pam_unix_cred(7), for interpretations of the keys
and values.
PAM_RHOST The remote host name.
PAM_RUSER The rlogin/rsh untrusted remote user name.
PAM_SERVICE The service name.
PAM_TTY The tty name.
PAM_USER The user name.
PAM_USER_PROMPT The default prompt used by pam_get_user().
PAM_REPOSITORY The repository that contains the authentication
token information.
The pam_repository structure is defined as:
struct pam_repository {
char *type; /* Repository type, e.g., files, */
/* nis, ldap */
void *scope; /* Optional scope information */
size_t scope_len; /* length of scope information */
};
The item_type PAM_SERVICE can be set only by pam_start() and is read-
only to both applications and service modules.
For security reasons, the item_type PAM_AUTHTOK and PAM_OLDAUTHTOK are
available only to the module providers. The authentication module,
account module, and session management module should treat PAM_AUTHTOK
as the current authentication token and ignore PAM_OLDAUTHTOK. The
password management module should treat PAM_OLDAUTHTOK as the current
authentication token and PAM_AUTHTOK as the new authentication token.
The pam_set_item() function is passed the authentication handle, pamh,
returned by pam_start(), a pointer to the object, item, and its type,
item_type. If successful, pam_set_item() copies the item to an internal
storage area allocated by the authentication module and returns
PAM_SUCCESS. An item that had been previously set will be overwritten
by the new value.
The pam_get_item() function is passed the authentication handle, pamh,
returned by pam_start(), an item_type, and the address of the pointer,
item, which is assigned the address of the requested object. The object
data is valid until modified by a subsequent call to pam_set_item() for
the same item_type, or unless it is modified by any of the underlying
service modules. If the item has not been previously set,
pam_get_item() returns a null pointer. An item retrieved by
pam_get_item() should not be modified or freed. The item will be
released by pam_end().
RETURN VALUES
Upon success, pam_get_item() returns PAM_SUCCESS; otherwise it returns
an error code. Refer to pam(3PAM) for information on error related
return values.

the multithreaded application uses its own PAM handle.

NOTES
If the PAM_REPOSITORY item_type is set and a service module does not
recognize the type, the service module does not process any informa‐
tion, and returns PAM_IGNORE. If the PAM_REPOSITORY item_type is not
set, a service module performs its default action.
PAM_AUSER is not intended as a replacement for PAM_USER. It is expected
to be used to supplement PAM_USER when there is an authenticated user
from a source other than pam_authenticate(3PAM). Such sources could be
sshd host-based authentication, kerberized rlogin, and su(8).
