Usage

    package Authenticate::Simple::Larry;
    
    use strict;
    use base 'Authen::Simple::Adapter';
    
    __PACKAGE__->options({
        secret => {
            type     => Params::Validate::SCALAR,
            default  => 'wall',
            optional => 1
        }
    });
    
    sub check {

        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'/ )
          if $self->log;
        
        return 0;
    }

Overview

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
        }
    });
