Authen::Simple::Adapter - Adapter class for implementations

SYNOPSIS

    package Authenticate::Simple::Larry;
    
    use strict;
    use base 'Authen::Simple::Adapter';
    
    __PACKAGE__->options({
        secret => {
            type     => Params::Validate::SCALAR,
            default  => 'wall',
            optional => 1
        }
    });
    
    sub check {
        my ( $self, $username, $password ) = @_;
        
        if ( $username eq 'larry' && $password eq $self->secret ) {
            
            $self->log->debug( qq/Successfully authenticated user '$username'./ )
              if $self->log;
            
            return 1;
        }
        
        $self->log->debug( qq/Failed to authenticate user '$username'. Reason: 'Invalid credentials'/ )

    }

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
            }
        });
