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 following: PAM_AUTHTOK The user authentication token. PAM_CONV The pam_conv structure. 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 application by pam_setcred(3PAM) or pam_open_session(3PAM). See the individual service module definitions, such as pam_unix_cred(5), for interpretations of the keys and values. PAM_RHOST The remote host name. PAM_RUSER The 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 previ- ously 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. ATTRIBUTES
See attributes(5) for description of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability | Stable | +-----------------------------+-----------------------------+ |MT-Level |MT-Safe with exceptions | +-----------------------------+-----------------------------+ The functions in libpam(3LIB) are MT-Safe only if each thread within the multithreaded application uses its own PAM handle.

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. SunOS 5.10 21 Jun 2004 pam_set_item(3PAM)
