DESCRIPTION

Adapter class for implementations.

METHODS

• new ( %parameters )

  If overloaded, this method should take a hash of parameters. The following options should be valid:

  • cache ( $ )

    Any object that supports get, set. Only successful authentications are cached.

    cache => Cache::FastMmap->new

  • callback ( \& )

    A subref that gets called with two scalar references, username and password.

    callback = sub {
        my ( $username, $password ) = @_;
        
        if ( length($$password) < 6 ) {
            return 0; # abort, invalid credintials
        }
        
        if ( $$password eq 'secret' ) {
            return 1; # abort, successful authentication
        }
        
        return; # proceed;
    }

  • log ( $ )

    Any object that supports debug, info, error and warn.

    log => Log::Log4perl->get_logger('Authen::Simple')
    log => $r->log
    log => $r->server->log

• init ( \%parameters )

  This method is called after construction. It should assign parameters and return the instance.

  sub init {
      my ( $self, $parameters ) = @_;
      
      # mock with parameters
      
      return $self->SUPER::init($parameters);
  }

• authenticate ( $username, $password )

  End user method. Applies callback, checks cache and calls check unless aborted by callback or a cache hit.

• check ( $username, $password )

  Must be implemented in sublcass, should return true on success and false on failure.

• check_password( $password, $encrypted )

• options ( \%options )

  Must be set in subclass, should be a valid Params::Validate specification. Accessors for options will be created unless defined in sublcass.

  __PACKAGE__->options({
      host => {
          type     => Params::Validate::SCALAR,
          optional => 0
      },
      port => {
          type     => Params::Validate::SCALAR,
          default  => 80,
          optional => 1
      }
  });
