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