NAME
    PlugAuth::Plugin::DBIAuth - DBI Authentication back end for PlugAuth

VERSION
    version 0.03

SYNOPSIS
    In your PlugAuth.conf file:

     ---
     plugins:
       - PlugAuth::Plugin::DBIAuth:
           db:
             dsn: 'dbi:SQLite:dbname=/path/to/dbfile.sqlite'
             user: ''
             pass: ''
           sql:
             init: 'CREATE TABLE IF NOT EXISTS users (username VARCHAR UNIQUE, password VARCHAR)'
             check_credentials: 'SELECT password FROM users WHERE username = ?'
             all_users: 'SELECT username FROM users'

DESCRIPTION
    This plugin provides an authentication mechanism for PlugAuth using any
    database supported by DBI as a backend. It is configured as above, with
    two hashes, db and sql.

  encryption
    Specifies the encryption method to use. This is only used when creating
    new users, or changing their passwords. Existing passwords will remain
    in their existing formats and will be decrypted automatically in the
    correct format.

    If provided, must be one of:

    *   unix

        Traditional UNIX crypt()

    *   unix_md5

        UNIX MD5

    *   apache_md5 [ default ]

        Apache MD5

  db
    The db hash provides the required parameters for the plugin needed to
    connect to the database.

   dsn
    The DNS passed into DBI. See the documentation for your database driver
    for the exact format (DBD::SQLite, DBD::Pg, DBD::mysql ... ).

   user
    The database user.

   pass
    The database password.

  sql
    The sql hash provides SQL statements which are executed for each
    operation. They are all optional. The examples shown here assumes a
    simple table with usernames and passwords:

     CREATE TABLE IF NOT EXISTS users (
       username VARCHAR UNIQUE,
       password VARCHAR
     );

   init
    Arbitrary SQL executed when the plugin is started.

   check_credentials
    The SQL statement used to fetch the encrypted password of a user. The
    username is the first bind value when executed. Example:

     SELECT password FROM users WHERE username = ?

   all_users
    The SQL statement used to fetch the list of users. Example:

     SELECT username FROM users

   create_user
    The SQL statement used to create a new user. Example:

     INSERT INTO users (username, password) VALUES (?,?)

   change_password
    The SQL statement used to change the password of an existing user.
    Example:

     UPDATE users SET password = ? WHERE username = ?

   delete_user
    The SQL statement used to delete an existing user. Example:

     DELETE FROM users WHERE username = ?

   dbh
    Returns the dbh handle used to query the database.

   created_encrypted_password
    Given a new plain text password, return the encrypted version.
