56 function is a null conversation function suitable
57 for applications that want to use PAM but don't support interactive
59 Such applications should set
61 to whatever authentication
62 token they've obtained on their own before calling
63 .Xr pam_authenticate 3
66 and their PAM configuration should specify the
68 option for all modules that require access to the
69 authentication token, to make sure they use
71 rather than try to query the user.
75 function returns one of the following values:
77 .It Bq Er PAM_CONV_ERR
81 .Xr openpam_ttyconv 3 ,
83 .Xr pam_authenticate 3 ,
92 function is an OpenPAM extension.
