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);

Macros

• pam_module
  Define entrypoints for the PAM module.

Structs

• Pam
  Opaque PAM handle, with additional native methods available via PamLibExt.
• PamFlags
• PamSendRef
  This sendable reference to Pam can be created via Pam::as_send_ref or From/Into.

Enums

• PamError
• PamMsgStyle

Traits

• PamData
  Trait to implement for data stored with pam using PamLibExt::send_data in order to provide a cleanup callback.
• PamLibExt
  Extension trait over Pam, usually provided by the libpam shared library.
• PamServiceModule
  Default service module implementation. All default functions return SERVICE_ERR. You can override functions depending on what kind of module you implement. See the respective pam_sm_* man pages for documentation.

Type Aliases

• PamCleanupCb
  Prototype of the callback used with PamLibExt::send_bytes
• PamResult
