NAME ^

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

SYNOPSIS ^

Plugin must be included in the Applications use statment.

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

Bigtop:

    config {
        engine MP20;
        template_engine TT;
        plugins AuthCookie;
        ...

There are various config options.

Apache Conf:

    <Location /controller>
        PerlSetVar auth_deny yes
        PerlSetVar auth_require valid-user
    </Location>

Gantry Conf:

    <GantryLocation /authcookie/sqlite/closed>
        auth_deny yes
        auth_require valid-user
    </GantryLocation>

Controller Config: (putting auth restictions on the method/action)

    sub controller_config {
        my ( $self ) = @_;
        {
            authed_methods => [
                { action => 'do_delete',  group => '' },
                { action => 'do_add',     group => '' },
                { action => 'do_edit',    group => '' },
            ],
        }
    } # END controller_config

Controller Config via Bigtop:

    method controller_config is hashref {
        authed_methods 
            do_delete   => ``,
            do_edit     => ``,
            do_add      => ``;
    }

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.

CONFIGURATION ^

Authentication can be turned on and off by setting 'auth_deny' or auth_optional.

    $self->auth_deny( 'yes' );

If 'yes', then validation is turned on and the particular location will require that the user is authed.

Just like Apache, you must define the type of auth, valid-user or group.

    $self->auth_require( 'valid-user' ); # default

    or

    $self->auth_require( 'group' );

After successful login the user row, groups (if any) will be set into the Gantry self object and can be retrieved using:

    $self->auth_user_row
    $self->auth_user_groups

For example, to access the username

$self->auth_user_row->username or whatever you have set for your auth_user_field see "Gantry::Plugins::AuthCookie#CONFIG OPTIONS"

And to access the groups

    my $groups = $self->auth_user_groups();
    
    foreach my $group ( keys %{ $groups } ) {
        print $group;
    } 

AuthCookie assumes that you have the following tables:

    table user (
        id          int,
        username    varchar,
        password    varchar,
    )
    
    table user_group (
        id      int,
        ident   int,    
    )
    
    # join table
    table user_groups (
        user
        user_group
    )

Optionally you can modify some the table expections like so:

    $self->auth_table( 'my_usertable' );
    $self->auth_user_field( 'myusername' );
    $self->auth_password_field( 'mypassword' );
    
    $self->auth_group_table( 'user_group' );
    $self->auth_group_join_table( 'user_user_group' );

CONFIG OPTIONS ^

    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
    auth_group_table    'user_group'
    auth_group_join_table 'user_groups'

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.

auth_execute_login
    $self->auth_execute_login( { user => 'joe', password => 'mypass' } );

This method can be called at anytime to log a user in.

auth_execute_logout
    $self->auth_execute_logout();

This method can be called at anytime to log a user out.

get_callbacks

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

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_login_url

accessor for auth_login_url. auth_login_url is a full/relative URL where the user will go after they login.

auth_cookie_name

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.
