NAME

Authen::SASL - SASL Authentication framework

SYNOPSIS

 use Authen::SASL;

 $sasl = Authen::SASL->new(
   mechanism => 'CRAM-MD5 PLAIN ANONYMOUS',
   callback => {
     pass => \&fetch_password,
     user => $user,
   }
 );

DESCRIPTION

SASL is a generic mechanism for authentication used by several network protocols. Authen::SASL provides an implementation framework that all protocols should be able to share.

The framework allows different implementations of the connection class to be plugged in. At the time of writing there were two such plugins.

Authen::SASL::Perl

This module implements several mechanisms and is implemented entirely in Perl.

Authen::SASL::Cyrus

This module uses the cyrus V1 C library.

CONTRUCTOR

The contructor may be called with or without arguments. Passing arguments is just a short cut to calling the mechanism and callback methods.

METHODS

mechanism

Returns the current list of mechanisms

mechanism NAMES

Set the list of mechanisms to choose from. NAMES should be a space separated string of the names.

callback NAME

Returns the current callback associated with NAME

callback NAME => VALUE, NAME => VALUE, ...

Sets the given callbacks to the given values

client_new SERVICE, HOST, SECURITY

Creates and returns a new connection object.

The Connection Class

client_start

The initial step to be performed. Returns the initial value to pass to the server or an empty list on error.

client_step CHALLENGE

This method is called when a response from the server requires it. CHALLENGE is the value from the server. Returns the next value to pass to the server or an empty list on error.

property NAME
property NAME => VALUE, NAME => VALUE
service

Returns the service argument that was passed to client_new

host

Returns the host argument that was passed to client_new

mechanism

Returns the name of the chosen mechanism.

Callbacks

There are three different ways in which a callback may be passed

CODEREF

If the value passed is a code reference then, when needed, it will be called and the connection object will be passed as the first argument.

ARRAYREF

If the value passed is an array reference, the first element in the array must be a code reference. When the callback is called the code reference will be called with the connection object passed as the first argument and all other values from the array passed after.

SCALAR

All other values passed will be used directly. ie it is the same as passing an code reference that, when called, returns the value.
