pam-client - Rust-style API to Pluggable Authentication Modules (PAM)

Usage

1. Add the following to your Cargo.toml: toml [dependencies] pam-client = "0.4"

2. Read the crate documentation

Functionality

The pam-client crate a safe API to the application-faced parts of PAM. This includes in detail:

• PAM authentication, account validation and session management
• PAM password changing
• Three sample conversation handler implementations
• Custom conversation handlers via trait implementation
• On-the-fly switching of the conversation handler
• Suspendable RAII session handling
• Methods for refreshing and reinitialization of PAM credentials
• PAM environment list support with easy integration to std::process::Command and nix::unistd::execve
• Getters and setters for all standard and most Linux-specific PAM items.
• Raw access methods for non-standard PAM items
• Errors mostly convertible to std::io::Error

Features

• cli: by default a conversation handler for command line applications is included. Disable this feature if you don't need it to remove a dependency on [rpassword].
• serde: enable this feature to get serde (de-)serialization support for the error, flag and token types and the default conversation handlers. Additionally EnvList becomes serializable into [(OsStr, OsStr)].

Supported Rust versions

The minimum supported Rust toolchain version is Rust 1.46.0.

Currently tested up to version 1.64.0-nightly.

Platform support

The pam-client crate is currently only tested on Linux, but support is implemented for Solaris and OpenPAM-based platforms like NetBSD.

Stability

This crate follows semantic versioning with the additional promise that below 1.0.0 backwards-incompatible changes will not be introduced with only a patch-level version number change.

Comparison with similar crates

This crate provides safe wrappers for the same library as [pam]. This crate aims to provide safe wrappers for different use cases at the expense of a slightly more complex interface, while [pam] provides an easier interface, but restricts the order of operations to the most common use cases.
