Connectivity

LdapRecord-Laravel comes with a built-in command to test connectivity to your LDAP servers. The exception message, error code, and diagnostic message are displayed after a failure to bind to your LDAP server.

To test your connectivity, run the following command:

php artisan ldap:test

Then, the following will be output:

Testing LDAP connection [default]...
+------------+------------+-----------------+-------------------------------------------------------------------------------------------------------------+---------------+
| Connection | Successful | Username        | Message                                                                                                     | Response Time |
+------------+------------+-----------------+-------------------------------------------------------------------------------------------------------------+---------------+
| default    | ✘ No       | user@local.com  | ldap_bind(): Unable to bind to server: Can't contact LDAP server. Error Code: [-1] Diagnostic Message: null | 5008.72ms     |
+------------+------------+-----------------+-------------------------------------------------------------------------------------------------------------+---------------+

The returned error codes and diagnostic messages can help you greatly when attempting to debug SSL and TLS connectivity issues.

TLS & SSL

TLS and SSL can be very tricky to get up and running. You will most likely have to place an ldap.conf file onto your local / production server to indicate that you would like to either bypass TLS / SSL certificate verification, or use a valid certificate that you have retrieved from your LDAP server.

This process is fully documented on the configuration documentation. It includes per OS level instructions on where your ldap.conf file is located (or where it must be created), as well as what it must contain.

Important: You must restart your web server after making changes to the ldap.conf file. In some cases, you may even have to restart your workstation or server for the changes to take effect.

Logging In

To debug issues logging in, its recommended to first complete the following steps:

  1. Enabled logging via the logging key inside of your config/ldap.php file
    (or by enabling it via your .env by using the LDAP_LOGGING key)
  2. Clear your configurations cache (if enabled) by running the php artisan config:clear command
  3. Add the ListensForLdapBindFailure trait onto your LoginController
  4. Attempt logging in again

After completing the above, the first thing to lookout for is whether a red error message is being displayed underneath your username / email field.

If you do not see any error message and are immediately returned back to the login page, then you have likely changed the username field on your resources/views/auth/login.blade.php but have not updated it inside of your LoginController, or vice versa.

For example, if you want users to login by a username instead of their email, make sure you've changed this via the username method, and the credentials method on your LoginController

// app/Http/Controllers/Auth/LoginController.php

use Illuminate\Http\Request;

public function username()
{
    // This is the name of the HTML 'input' inside
    // of our 'login.blade.php' view:
    return 'username';
}

protected function credentials(Request $request)
{
    // 'samaccountname' is the attribute we are using to
    // locate users in our LDAP directory with. The
    // value of the key must be the input name of
    // our HTML input, as shown above:
    return [
        'samaccountname' => $request->get('username'),
        'password' => $request->get('password'),
    ];
}

If you simply see an Invalid Credentials, or Can't contact LDAP server error, refer to your log files inside of your applications storage/logs directory to investigate further. With logging enabled, all LDAP searches, binds, failures and exceptions will be reported there.
