MultiAuth module
================

The MultiAuth module provides a method for authenticating users agains
a list of authentication sources. There is only one authentication
module:

`multiauth:MultiAuth`
: Authenticate the user against a list of authentication sources.


`multiauth:MultiAuth`
---------------------

This module is useful when you want to let the users decide which
authentication source fits better their needs at any scenario. For
example, they can choose the `saml` authentication source in most
cases and then switch to the `admin` authentication source when
'saml' is down for some reason.

To create a MultiAuth authentication source, open
`config/authsources.php` in a text editor, and add an entry for the
authentication source:

    'example-multi' => array(
        'multiauth:MultiAuth',

        /*
         * The available authentication sources.
         * They must be defined in this authsources.php file.
         */
        'sources' => array('example-saml', 'example-admin'),
    ),

    'example-saml' => array(
        'saml:SP',
        'entityId' => 'my-entity-id',
        'idp' => 'my-idp',
    ),

    'example-admin' => array(
        'core:AdminPassword',
    ),

You should update the name of this authentication source
(`example-multi`), and the authentication sources it references,
to have a name which makes sense to your organization.

The MultiAuth authentication sources only has an option: the
`sources` option, and it is required. It is an array of other
authentication sources defined in the `config/authsources.php`
file. The order in this array does not matter since the user
is the one that decides which one to use.
