SYNOPSIS


.In sys/types.h
.In security/pam_appl.h
.In security/openpam.h "int" openpam_nullconv "int n" "const struct pam_message **msg" "struct pam_response **resp" "void *data"

DESCRIPTION

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.

RETURN VALUES

The openpam_nullconv function returns one of the following values:
[PAM_CONV_ERR]
Conversation failure.
