NAME

       pam_sm_setcred - PAM service function to alter credentials

SYNOPSIS

       #define PAM_SM_AUTH

       #include <security/pam_modules.h>

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

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.

RETURN VALUES

       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().
