Presentation
|
|
------------
|
|
|
|
By default, only the configured authentication backend is available for
|
|
users.
|
|
|
|
Contrary to :doc:`multiple backend stacking<authmulti>`, backend choice
|
|
will present all available authentication methods to users, who will
|
|
choose the one they want.
|
|
|
|
The choice will concern three backends:
|
|
|
|
- Authentication
|
|
- Users
|
|
- Password
|
|
|
|
The chosen backends will be registered in session:
|
|
|
|
- ``$_auth``
|
|
- ``$_userDB``
|
|
- ``$_passwordDB``
|
|
|
|
Authentication choice will also be registered in session:
|
|
|
|
- ``$_authChoice``
|
|
|
|
Configuration
|
|
-------------
|
|
|
|
In Manager, go in ``General Parameters`` > ``Authentication modules``
|
|
and choose Choice for authentication.
|
|
|
|
|
|
.. attention::
|
|
|
|
When ``Choice`` is selected for authentication, values
|
|
for Users and Password modules are also forced to ``Choice``.
|
|
|
|
Then, go in ``Choice Parameters``:
|
|
|
|
- **URL parameter**: parameter name used to set choice value (default:
|
|
``lmAuth``)
|
|
- **AuthBasic handler parameter**: authentication module used by
|
|
AuthBasic handler
|
|
- **Allowed modules**: click on ``New chain`` to add a choice.
|
|

|
|
|
|
Define here:
|
|
|
|
- **Name**: Text displayed on choice tab.
|
|
- **Authentication module**
|
|
- **Users module**
|
|
- **Password module**
|
|
- **URL**: optional, can be used to redirect on another URL (for
|
|
example https://authssl.example.com). This is mandatory if you want
|
|
to use an Apache authentication module, which is run by Apache before
|
|
showing the LemonLDAP::NG portal page.
|
|
- **Condition**: optional, can be used to evaluate an expression to
|
|
display the tab. For example, to display a tab only if redirected by
|
|
Handler from application ``test1.example.com``, you can set this
|
|
condition:
|
|
|
|
.. code-block:: perl
|
|
|
|
$env->{urldc} =~ /test1\.example\.com/
|
|
|
|
|
|
.. note::
|
|
|
|
Authentication request to an another URL than Portal URL can lead
|
|
to a persistent loop between Portal and a redirection URL (pdata is not
|
|
removed because domains mismatch). To avoid this, you have to set pdata
|
|
cookie domain by editing ``lemonldap-ng.ini`` in section [portal]:
|
|
|
|
.. code:: ini
|
|
|
|
[portal]
|
|
pdataDomain = example.com
|
|
|
|
|
|
|
|
|
|
.. tip::
|
|
|
|
You can prefix the key name with a digit to order them. The
|
|
digit will not be shown on portal page. Underscore characters are also
|
|
replaced by spaces.
|
|
|
|
|
|
.. tip::
|
|
|
|
You can also override some LLNG parameters for each chain. See
|
|
:doc:`Parameter list<parameterlist>` to have the key names to use
