Informations about the package laravel-ldap
Adldap2 Laravel middleware
The excellent Adldap2-Laravel package makes it super simple to integrate your Laravel application with an LDAP server to authenticate your users, but as these users can be managed externally to your application, it's not always possible to manage their access if they are already logged in.
This package not only allows you to define groups your users must belong to in order to authenticate, but will also ensure that those groups continue to exist throughout a user's authenticated session, not just at the time of authentication i.e. when they log in.
Installation
composer require dyrynda/laravel-ldap
Once the package is installed, publish the configuration file
php artisan vendor:publish --tag="laravel-ldap"
Configuration
The three keys you are likely to change are allowed_groups
, username
, and password_expiry_threshold
.
allowed_groups
contains the distinguished names for allowed groups that users must have in order to be able to authenticate.username
is the database field that your application users can be found by in theusers
table, and will match the username used to authenticate with your application.password_expiry_threshold
is used to determine when a password was last changed, relative to the authenticated user's (cached) data.
Usage
In order to restrict authentication of users to your application using the allowed_groups
key, add the GroupAccessScope
to the scopes
key of the adldap_auth
configuration file. A user will only be able to authenticate if they are a member of each group defined in the allowed_groups
array.
This scope will ensure that users can only login if they are members of the given groups, but does nothing to protect your application from users that are already logged in from accessing it should their access be revoked in the directory server.
To combat this, you can add the following to to the $routeMiddleware
property of your app/Http/Kernel.php
.
'ldap' => \Dyrynda\Ldap\Http\Middleware\LdapMiddleware::class
This middleware can then be applied to your routes to ensure the following:
- Your LDAP user exists in the directory and continues to be a member of the
allowed_groups
- Authenticated users have not recently changed their password
- Authenticated users' passwords are not due to expire within a configured period of time, which defaults to 5 days
Should any of these conditions evaluate to false, the user will be logged out and directed to login to your application again.
Updated password
If you wish to log users out based on their password being updated, you must cache the timestamp which marks the last time the password was updated (on login). When the value in LDAP is newer than the value in your application's cache, the user will be logged out.
If the configured password_expiration_field
attribute does not exist on your User
model, this check will be skipped.
You will need to configure modify the adldap_auth.php
configuration file to sync the pwdlastset
value from LDAP.
Ensure you have a the corresponding database field configured.
Testing
By default ldap is enabled for testing, this can be toggled within the config laravel_ldap.php
Lastly, update the password_expiration_field
(if not using the default password_updated_at
) in your laravel_ldap.php
configuration file.
