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:

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.
