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.
SEE ALSO

STANDARDS
The openpam_nullconv function is an
OpenPAM extension.
