Struct pam_client::conv_null::Conversation

pub struct Conversation {}

Null implementation of ConversationHandler

When a PAM module asks for any user interaction an error is returned. Error and info messages are and ignored.

This handler may be used for testing and for environments where no user interaction is possible, no credentials can be stored beforehand and failing is the only answer if some PAM module needs input.
