NAME

Gantry::Plugins::AuthCookie - Plugin for cookie based authentication

SYNOPSIS

In Apache Perl startup or app.cgi or app.server:

<Perl>
    # ...
    use MyApp qw{
            -Engine=CGI
            -TemplateEngine=TT
            -PluginNamespace=your_module_name
            AuthCookie
    };
</Perl>

Inside MyApp.pm:

use Gantry::Plugins::AuthCookie;

sub namespace {
    return 'your_module_name';
    # the string is up to you, but needs to match -PluginNamespace
}

DESCRIPTION

This plugin mixes in a method that will supply the login routines and accessors that will store the authed user row and user groups.

Note that you must include AuthCookie in the list of imported items when you use your base app module (the one whose location is app_rootp). Failure to do so will cause errors.

You also need a namespace method in the base module. The namespace is up to you, but don't pick 'Gantry'. The namespace will be used to register callbacks for this plugin. If you don't set a namespace, all apps in the apache instance with your app will have to use the AuthCookie plugin, or they will die horrible deaths for lack of accessors, while they are being needlessly subjected to auth.

CONFIGURATION

Authentication can be turned on and off by setting 'auth_deny'. If 'on', then validation is turned on and the particular location will require that the user is authed. After the successful login the user row and the user groups ( if any ) will be set into the Gantry site object and can be retrieved using the $self->auth_user_row and $self->auth_user_groups accessors.

auth_deny           'no' / 'yes'              # default 'off'
auth_table          'user_table'              # default 'user'
auth_file           '/path/to/htpasswd_file'  # Apache htpasswd file
auth_user_field     'ident'                   # default 'ident'
auth_password_field 'password'                # default 'password'
auth_require        'valid-user' or 'group'   # default 'valid-user'
auth_groups         'group1,group2'           # allow these groups
auth_secret         'encryption_key'          # default 'w3s3cR7'
auth_cookie_name    'my_auth_cookie'          # default 'auth_cookie'
auth_cookie_domain  'www.example.com'         # default URL full domain

METHODS

do_login

this method provides the login form and login routines.

auth_user_row

This is mixed into the gantry object and can be called retrieve the DBIC user row.

auth_user_groups

This is mixed into the gantry object and can be called to retrieve the defined groups for the authed user.

get_callbacks

For use by Gantry.pm. Registers the callbacks needed to auth pages during PerlHandler Apache phase or its moral equivalent.

CONFIGURATION ACCESSORS

auth_deny

accessor for auth_deny. Turns authentication on when set to 'on'.

auth_optional

accessor for auth_optional. User validation is active when set to 'on'.

auth_table

accessor for auth_table. Tells AuthCookie the name of the user table. default is 'user'.

auth_file

accessor for auth_file. Tells AuthCookie to use the Apache style htpasswd file and where the file is located.

auth_user_field

accessor for auth_user_field. Tells AuthCookie the name of the username field in the user database table.

auth_password_field

accessor for auth_password_field. Tells AuthCookie the name of the password field in the user database table.

auth_require

accessor for auth_require. Tells AuthCookie the type of requirement for the set authentication. It's either 'valid-user' (default) or 'group'

auth_groups

accessor for auth_groups. This tells AuthCookie which groups are allowed which is enforced only when auth_require is set to 'group'. You can supply multiple groups by separating them with commas.

auth_secret

accessor for auth_secret. auth_secret is the encryption string used to encrypt the cookie. You can supply your own encryption string or just use the default the default value.

auth_logout_url

accessor for auth_logout_url. auth_logout_url is a full URL where the user will go when they log out. Logging out happens when the do_login method is called with a query_string parameter logout=1.

accessor for name of auth cookie. By default the cookie is called 'auth_cookie'. Import this and define a conf variable of the same name to change the cookie's name.

accessor for the auth cookie's domain. By default undef is used, so the cookie will be set on the fully qualified domain of the login page. Import this method and define a conf variable of the same name to change the domain.
