NAME

Jifty::Plugin::Authentication::Ldap - LDAP Authentication Plugin for Jifty

DESCRIPTION

CAUTION: This plugin is experimental.

This may be combined with the User Mixin to provide user accounts and ldap password authentication to your application.

When a new user authenticates using this plugin, a new User object will be created automatically. The name and email fields will be automatically populated with LDAP data.

in etc/config.yml

  Plugins: 
    - Authentication::Ldap: 
       LDAPhost: ldap.univ.fr           # ldap server
       LDAPbase: ou=people,dc=.....     # base ldap
       LDAPName: displayname            # name to be displayed (cn givenname)
       LDAPMail: mailLocalAddress       # email used optional
       LDAPuid: uid                     # optional

Then create a user model

  jifty model --name=User

and edit lib/App/Model/User.pm to look something like this:

  use strict;
  use warnings;
  
  package Venice::Model::User;
  
  use Jifty::DBI::Schema;
  use Venice::Record schema {
        # More app-specific user columns go here
  };
  
  use Jifty::Plugin::User::Mixin::Model::User;
  use Jifty::Plugin::Authentication::Ldap::Mixin::Model::User;
  
  sub current_user_can {
      my $self = shift;
      my $type = shift;
      my %args = (@_);
      
    return 1 if
          $self->current_user->is_superuser;
    
    # all logged in users can read this table
    return 1
        if ($type eq 'read' && $self->current_user->id);
    
    return $self->SUPER::current_user_can($type, @_);
  };
  
  1;

ACTIONS

This plugin will add the following actions to your application. For testing you can access these from the Admin plugin.

Jifty::Plugin::Authentication::Ldap::Action::LDAPLogin

The login path is /ldaplogin.

Jifty::Plugin::Authentication::Ldap::Action::LDAPLogout

The logout path is /ldaplogout.

METHODS

prereq_plugins

This plugin depends on the User Mixin.

Configuration

The following options are available in your config.yml under the Authentication::Ldap Plugins section.

LDAPhost

Your LDAP server.

LDAPbase

[Mandatory] The base object where your users live. If LDAPBindTemplate is defined, LDAPbase is only used for user search.

LDAPBindTemplate

Alternatively to LDAPbase, you can specify here the whole DN string, with %u as a placeholder for UID.

LDAPMail

The DN that your organization uses to store Email addresses. This gets copied into the User object as the email.

LDAPName

The DN that your organization uses to store Real Name. This gets copied into the User object as the name.

LDAPuid

The DN that your organization uses to store the user ID. Usually cn. This gets copied into the User object as the ldap_id.

LDAPOptions

These options get passed through to Net::LDAP.

Default Options :

 debug   => 0
 onerror => undef
 async   => 1 

Other options you may want :

 timeout => 30

See Net::LDAP for a full list. You can overwrite the defaults selectively or not at all.

LDAPLoginHooks

Optional list of Perl functions that would be called after a successful login and after a corresponding User object is loaded and updated. The function is called with a hash array arguments, as follows:

  username => string
  user_object => User object
  ldap => Net::LDAP object
  infos => User attributes as returned by get_infos  

LDAPFetchUserAttr

Optional list of LDAP user attributes fetched by get_infos. The values are returned to the login hook as arrayrefs.

Example

The following example authenticates the application against a MS Active Directory server for the domain MYDOMAIN. Each user entry has the attribute 'department' which is used for authorization. LDAPbase is used for user searching, and binding is done in a Microsoft way. The login hook checks if the user belongs to specific departments and updates the user record.
