DESCRIPTION ^

Dancer::Plugin::Auth::RBAC is an authentication framework and role-based access control system. As a role-based access control system Dancer::Plugin::Auth::RBAC can be complex but will give you the most flexibilty over all other access control philosophies.

The Dancer::Plugin::Auth::RBAC plugin provides your application with the ability to easily authenticate and restrict access to specific users and groups by providing a tried and tested RBAC (role-based access control) system. Dancer::Plugin::Auth::RBAC provides this level of sophistication with minimal configuration.

Dancer::Plugin::Auth::RBAC exports the auth() and authd() keywords:

    $auth = auth($login, $pass)     # new authorization instance
    $auth->asa($role)               # check if the authenticated user has the specified role
    $auth->can($operation)          # check if the authenticated user has permission
    $auth->can($operation, $action) # to perform a specific action
    $auth->roles(@roles)            # get or set roles for the current logged in user
    $auth->errors()                 # authentication errors if any
    $auth->revoke()                 # revoke authorization (logout)
    
    return authd()                  # is the current user authorized?

The Dancer::Plugin::Auth::RBAC authentication framework relies on the Dancer::Plugin::Auth::RBAC::Credentials namespace to do the actual authentication, and likewise relies on the Dancer::Plugin::Auth::RBAC::Permissions namespace to handle access control. The following configuration example is based on Dancer::Plugin::Auth::RBAC::Credentials::Config and Dancer::Plugin::Auth::RBAC::Permissions::Config. This framework also ship with Dancer::Plugin::Auth::RBAC::Credentials::SQLite, Dancer::Plugin::Auth::RBAC::Credentials::MySQL, Dancer::Plugin::Auth::RBAC::Credentials::PostrgeSQL which are arguably easier to setup and utilize.
