Синопсис (Synopsis)

#define PAM_SM_AUTH

       #include <security/pam_modules.h>

       int pam_sm_setcred(pam_handle_t *pamh, int flags, int argc,
                          const char **argv);

Описание (Description)

The pam_sm_setcred function is the service module's
       implementation of the pam_setcred(3) interface.

       This function performs the task of altering the credentials of
       the user with respect to the corresponding authorization scheme.
       Generally, an authentication module may have access to more
       information about a user than their authentication token. This
       function is used to make such information available to the
       application. It should only be called after the user has been
       authenticated but before a session has been established.

       Valid flags, which may be logically OR'd with PAM_SILENT, are:

       PAM_SILENT
           Do not emit any messages.

       PAM_ESTABLISH_CRED
           Initialize the credentials for the user.

       PAM_DELETE_CRED
           Delete the credentials associated with the authentication
           service.

       PAM_REINITIALIZE_CRED
           Reinitialize the user credentials.

       PAM_REFRESH_CRED
           Extend the lifetime of the user credentials.

       The way the auth stack is navigated in order to evaluate the
       pam_setcred() function call, independent of the pam_sm_setcred()
       return codes, is exactly the same way that it was navigated when
       evaluating the pam_authenticate() library call. Typically, if a
       stack entry was ignored in evaluating pam_authenticate(), it will
       be ignored when libpam evaluates the pam_setcred() function call.
       Otherwise, the return codes from each module specific
       pam_sm_setcred() call are treated as required.

Возвращаемое значение (Return value)

PAM_CRED_UNAVAIL
           This module cannot retrieve the user's credentials.

       PAM_CRED_EXPIRED
           The user's credentials have expired.

       PAM_CRED_ERR
           This module was unable to set the credentials of the user.

       PAM_SUCCESS
           The user credential was successfully set.

       PAM_USER_UNKNOWN
           The user is not known to this authentication module.

       These, non-PAM_SUCCESS, return values will typically lead to the
       credential stack failing. The first such error will dominate in
       the return value of pam_setcred().
