71 * The =openpam_nullconv function is a null conversation function suitable
72 * for applications that want to use PAM but don't support interactive
73 * dialog with the user.  Such applications should set =PAM_AUTHTOK to
74 * whatever authentication token they've obtained on their own before
75 * calling =pam_authenticate and / or =pam_chauthtok, and their PAM
76 * configuration should specify the ;use_first_pass option for all modules
77 * that require access to the authentication token, to make sure they use
78 * =PAM_AUTHTOK rather than try to query the user.
