python3-simplepam

An interface to the Pluggable Authentication Modules (PAM) library on linux, written in pure python (using ctypes)

Overview

This module provides an authenticate function that allows the caller to authenticate a given username / password against the PAM system on Linux.

Usage

Run python3 setup.py install as root to install the module, then import the authenticate function, and use it as follows:

    from simplepam import authenticate
    authenticate(username, password, service)

The full function signature is as follows:

    authenticate(username, password, service='login', encoding='utf-8',
                 resetcred=True)

The service argument specifies the PAM service to authenticate against. Defaults to login.

username, password and service can be given as strings or bytes. If they are strings, they will be encoded using the encoding given by the encoding parameter, or, if omitted, as UTF-8.

The function returns True if the authentication succeeds and returns False if authentication fails (or if PAM returns an error (FIXME)).
