.Dd December 21, 2007 .Dt OPENPAM_NULLCONV 3 .Os .Sh NAME .Nm openpam_nullconv .Nd null conversation function .Sh LIBRARY .Lb libpam .Sh SYNOPSIS n sys/types.h n security/pam_appl.h n security/openpam.h .Ft "int" .Fn openpam_nullconv "int n" "const struct pam_message **msg" "struct pam_response **resp" "void *data" .Sh DESCRIPTION The .Nm 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 .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.
