Crate pamsm

PAM Service Module wrappers

Usage

For example, here is a time based authentication module :

#[macro_use] extern crate pamsm;
extern crate time;

use pamsm::{PamServiceModule, Pam, PamFlags, PamError};

struct PamTime;

impl PamServiceModule for PamTime {
    fn authenticate(pamh: Pam, _: PamFlags, args: Vec<String>) -> PamError {
        let hour = time::OffsetDateTime::now_utc().hour();
        if hour != 4 {
            // Only allow authentication when it's 4 AM
            PamError::SUCCESS
        } else {
            PamError::AUTH_ERR
        }
    }
}

pam_module!(PamTime);
