NAME

       Dancer::Plugin::Auth::Extensible::Database - authenticate via a database

DESCRIPTION

       This class is an authentication provider designed to authenticate users against a
       database, using Dancer::Plugin::Database to access a database.

       Crypt::SaltedHash is used to handle hashed passwords securely; you wouldn't want to store
       plain text passwords now, would you?  (If your answer to that is yes, please reconsider;
       you really don't want to do that, when it's so easy to do things right!)

       See Dancer::Plugin::Database for how to configure a database connection appropriately; see
       the "CONFIGURATION" section below for how to configure this authentication provider with
       database details.

       See Dancer::Plugin::Auth::Extensible for details on how to use the authentication
       framework, including how to pick a more useful authentication provider.

CONFIGURATION

       This provider tries to use sensible defaults, so you may not need to provide much
       configuration if your database tables look similar to those in the "SUGGESTED SCHEMA"
       section below.

       The most basic configuration, assuming defaults for all options, and defining a single
       authentication realm named 'users':

           plugins:
               Auth::Extensible:
                   realms:
                       users:
                           provider: 'Database'

       You would still need to have provided suitable database connection details to
       Dancer::Plugin::Database, of course;  see the docs for that plugin for full details, but
       it could be as simple as, e.g.:

           plugins:
               Auth::Extensible:
                   realms:
                       users:
                           provider: 'Database'
               Database:
                   driver: 'SQLite'
                   database: 'test.sqlite'

       A full example showing all options:

           plugins:
               Auth::Extensible:
                   realms:
                       users:
                           provider: 'Database'
                           # optionally set DB connection name to use (see named
                           # connections in Dancer::Plugin::Database docs)
                           db_connection_name: 'foo'

                           # Optionally disable roles support, if you only want to check
                           # for successful logins but don't need to use role-based access:
                           disable_roles: 1

                           # optionally specify names of tables if they're not the defaults
                           # (defaults are 'users', 'roles' and 'user_roles')
                           users_table: 'users'
                           roles_table: 'roles'
                           user_roles_table: 'user_roles'

                           # optionally set the column names (see the SUGGESTED SCHEMA
                           # section below for the default names; if you use them, they'll
                           # Just Work)
                           users_id_column: 'id'
                           users_username_column: 'username'
                           users_password_column: 'password'
                           roles_id_column: 'id'
                           roles_role_column: 'role'
                           user_roles_user_id_column: 'user_id'
                           user_roles_role_id_column: 'roles_id'

       See the main Dancer::Plugin::Auth::Extensible documentation for how to configure multiple
       authentication realms.

SUGGESTED SCHEMA

       If you use a schema similar to the examples provided here, you should need minimal
       configuration to get this authentication provider to work for you.

       The examples given here should be MySQL-compatible; minimal changes should be required to
       use them with other database engines.

   users table
       You'll need a table to store user accounts in, of course.  A suggestion is something like:

           CREATE TABLE users (
               id       INTEGER     AUTO_INCREMENT PRIMARY KEY,
               username VARCHAR(32) NOT NULL       UNIQUE KEY,
               password VARCHAR(40) NOT NULL
           );

       You will quite likely want other fields to store e.g. the user's name, email address, etc;
       all columns from the users table will be returned by the "logged_in_user" keyword for your
       convenience.

   roles table
       You'll need a table to store a list of available roles in (unless you're not using roles -
       in which case, disable role support (see the "CONFIGURATION" section).

           CREATE TABLE roles (
               id    INTEGER     AUTO_INCREMENT PRIMARY KEY,
               role  VARCHAR(32) NOT NULL
           );

   user_roles table
       Finally, (unless you've disabled role support)  you'll need a table to store user <-> role
       mappings (i.e. one row for every role a user has; so adding extra roles to a user consists
       of adding a new role to this table).  It's entirely up to you whether you use an "id"
       column in this table; you probably shouldn't need it.

           CREATE TABLE user_roles (
               user_id  INTEGER  NOT NULL,
               role_id  INTEGER  NOT NULL,
               UNIQUE KEY user_role (user_id, role_id)
           );

       If you're using InnoDB tables rather than the default MyISAM, you could add a foreign key
       constraint for better data integrity; see the MySQL documentation for details, but a table
       definition using foreign keys could look like:

           CREATE TABLE user_roles (
               user_id  INTEGER, FOREIGN KEY (user_id) REFERENCES users (id),
               role_id  INTEGER, FOREIGN_KEY (role_id) REFERENCES roles (id),
               UNIQUE KEY user_role (user_id, role_id)
           ) ENGINE=InnoDB;
