Such applications should set .Dv PAM_AUTHTOK to whatever authentication token they've obtained on their own before calling .Xr pam_authenticate 3 and / or .Xr pam_chauthtok 3 , and their PAM configuration should specify the .Dv use_first_pass option for all modules that require access to the authentication token, to make sure they use .Dv PAM_AUTHTOK rather than try to query the user. .Sh RETURN VALUES The .Fn openpam_nullconv function returns one of the following values: l -tag -width 18n t Bq Er PAM_SUCCESS Success. t Bq Er PAM_CONV_ERR Conversation failure. .El .Sh SEE ALSO .Xr openpam_ttyconv 3 , .Xr pam 3 , .Xr pam_authenticate 3 , .Xr pam_chauthtok 3 , .Xr pam_prompt 3 , .Xr pam_set_item 3 , .Xr pam_strerror 3 , .Xr pam_vprompt 3 .Sh STANDARDS The .Fn openpam_nullconv function is an OpenPAM extension. .Sh AUTHORS The .Fn openpam_nullconv function and this manual page were developed for the .Fx Project by ThinkSec AS and Network Associates Laboratories, the Security Research Division of Network Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035
