openpam_nullconv -- null conversation function
openpam_nullconv(int n, const struct pam_message **msg,
struct pam_response **resp, void *data);
The openpam_nullconv() function is a null conversation function suitable
for applications that want to use PAM but don't support interactive
dialog with the user. Such applications should set PAM_AUTHTOK to
whatever authentication token they've obtained on their own before
calling pam_authenticate(3) and / or pam_chauthtok(3), and their PAM
configuration should specify the use_first_pass option for all modules
that require access to the authentication token, to make sure they use
PAM_AUTHTOK rather than try to query the user.
The openpam_nullconv() function returns one of the following values:
[PAM_CONV_ERR] Conversation failure.
openpam_ttyconv(3), pam(3), pam_authenticate(3), pam_chauthtok(3),
pam_prompt(3), pam_set_item(3), pam_strerror(3), pam_vprompt(3)
The openpam_nullconv() function is an OpenPAM extension.
The openpam_nullconv() function and this manual page were developed for
the FreeBSD Project by ThinkSec AS and Network Associates Laboratories,
the Security Research Division of Network Associates, Inc. under
DARPA/SPAWAR contract N66001-01-C-8035 (``CBOSS''), as part of the DARPA
CHATS research program.
The OpenPAM library is maintained by Dag-Erling Smorgrav <firstname.lastname@example.org>.
