Howto contribute or support the extension

As you as delevoper know, it's not only source code that matters. The best code is worthless if no documentation exists. My focus is to provide a comprehensive documentation for this extension. This should help YOU to do your task fast and without strugle. Updating this extension take days starting with programming, writing the docs and write test for the code and the docs.

I'am glad to see that many persons use the plugin!

If you want to help you can do the following:

  • Extend or correct the docs and create a Pull-Request
  • Fix or extend the plugins source code and create a Pull-Request
  • Add further tests and create a Pull-Request
  • Open a issue for questions or problems

If this project help you reduce time to develop, you can spend me a cup of coffee :)

Keep this in mind if you are browsing the GitHub Repository of Adldap2

Functions of the extension

It has been a long way since 29. Jan 2014, many functions has been added. I noticed for myself that a short overview might help everyone to see whats possible.

The simple Method 1

  • Query only informations from Active Directory.

The deep integration with Method 2

Create, modify or delete Active Directory objects with Method 3: https://github.com/edvler/yii2-adldap-module/blob/master/docs/CREATE_MODIFY_DELETE_OBJECTS.md

  • Thanks to Adldap2, it's easy to create, modify or delete objects.

How to start??

  • My suggestion is that you should start with Method 1. Start with a configration as described below and do some simple querys. If you see how it works, you can try Method 2.

If you have some questions...

Usage - Method 1, Method 2 and Method 3

Usage method 1: Simple usage without a user model

If you are need to query some informations for a user from the Active Directory this would be best way. No additional configuration is needed and the only thing to do is to add the configuration as described above to your components section.

You only use the extension in the regular Yii2 style:

//...
$un = 'testuser';

/*
There are three ways available to call Adldap2 function.
If you use more providers (multiple Active Directory connections)
you make one as default and you can call this one with Method1 or Method2
and the second one will be called with Method3.
*/

//Get the Ldap object for the user.
//$ldapObject holds a class of type Adldap\Models\User from the Adldap project!
// Method 1: uses the default provider given in the configuration above (array key defaultProvider)
$ldapObject = \Yii::$app->ad->search()->findBy('sAMAccountname', $un);
// Method 2: uses the default provider given in the configuration above (array key defaultProvider)
$ldapObject = \Yii::$app->ad->getDefaultProvider()->search()->findBy('sAMAccountname', $un);
// Method 3: get the provider by name (here name default is used).
$ldapObject = \Yii::$app->ad->getProvider('default')->search()->findBy('sAMAccountname', $un);

//Examples
//Please note that all fields from ldap are arrays!
//Access it with ..[0] if it is a single value field.
$givenName = $ldapObject['givenname'][0];
$surname = $ldapObject['surname'][0];
$displayname = $ldapObject['displayname'][0];
$telephone = $ldapObject['telephonenumber'][0];

echo 'gn: ' . $givenName . ' sn: ' . $surname . 
 ' dispname: ' . $displayname . ' phone: ' . $telephone;

//Print all possible attributes
echo '<pre>' . print_r($ldapObject,true) . '</pre>';

// More ways to get attributes: 
// https://github.com/Adldap2/Adldap2/blob/master/docs/models/model.md#getting-attributes

Further documentation with examples: https://github.com/edvler/yii2-adldap-module/blob/master/docs/USAGE_WITHOUT_USER_MODEL.md


Usage method 2: Deep integration into the yii2 framework with a user model

The second method gives you the ability to authenticate users against Active Directory with a special user model. It intgerates very well into the RBAC security concept of yii2 (http://www.yiiframework.com/doc-2.0/guide-security-authorization.html#rbac).

You can use all features of the yii2 user integration.

Some Examples:

//...
//Has user a permission?
$hasPermission = \Yii::$app->user->can('permissionDisplayDetailedAbout');

//Query informations from Active Directory. You can use in a controller, a view, everywhere in yii2!
if (!\Yii::$app->user->isGuest) {
    //Get the yii2 identitiy, which was set by the Yii::$app->user->login(..,..) function
    //See model/LoginForm.php in the basic template for the login logic
    $yii2IdentityObject = \Yii::$app->user->identity;

    $rolesOfUser = \Yii::$app->authManager->getRolesByUser($yii2IdentityObject->getId());
    echo '<pre>' . print_r($rolesOfUser,true) . '</pre>';

    //Get the Ldap object for the user.
    //$ldapObject holds a class of type Adldap\Models\User from the Adldap project!
    //No performance issues, because the queryLdapUserObject function uses a cache.
    $ldapObject = $yii2IdentityObject->queryLdapUserObject();

    //Examples
    //Please note that all fields from ldap are arrays!
    //Access it with ..[0] if it is a single value field.
    $givenName = $ldapObject['givenname'][0];
    $surname = $ldapObject['surname'][0];
    $displayname = $ldapObject['displayname'][0];
    $telephone = $ldapObject['telephonenumber'][0];

    echo 'gn: ' . $givenName . ' sn: ' . $surname . 
         ' dispname: ' . $displayname . ' phone: ' . $telephone;

    //Print all possible attributes
    echo '<pre>' . print_r($ldapObject,true) . '</pre>';

    // More ways to get attributes:
    // https://github.com/Adldap2/Adldap2/blob/master/docs/models/model.md#getting-attributes
}
//...

If you use the Edvlerblog\Adldap2\model\UserDbLdap.php class you can do things like login with a user into yii2 without createing them in yii2. Tasks like creating a user, assigning roles and check password against Active Directory all automatically done from Edvlerblog\Adldap2\model\UserDbLdap.php class.

For example imagine the following:

  • You create a user in Active Directory and assign this user to a group starting with yii2_ (e.g. yii2_example_group).
  • In yii2 a role with the same name exists (yii2_example_group). The role has some permissions assigned.

If you try to login with your new user, the user is created automatically in yii2 and role yii2_example_group is assigned automatically on login.
For the user this is transparent. The only feedback to the user is a successull login and that it is possible to use the functions which he has permissions to access.

Further documentation with setup and examples: https://github.com/edvler/yii2-adldap-module/blob/master/docs/USAGE_WITH_USER_MODEL.md


Usage method 3: Create, modify and delete Active Directory objects

Adldap2 offers the option to create, modify and delete Active Directory objects. See https://github.com/Adldap2/Adldap2/blob/master/docs/models/model.md for documentation.

Prequesits

  • To create or modify attributes of a Active Directory object use a bind user in your configuration with rights to change the attributes of the objects (a dirty but very discourraged way is to add the bind user to the domain-admins group)!
  • For some actions like change password you need a SSL/TLS connection. See configuration for further hints.

One example: Modify the displayname of a user

// https://github.com/Adldap2/Adldap2/blob/master/docs/models/model.md#updating-attributes
// Step 1: Query the ldap object (via method 1 or method 2) 
$un = 'testuser';
$ldapObject = \Yii::$app->ad->getProvider('default')->search()->findBy('sAMAccountname', $un);

// Step 2: Update the attribute
// https://github.com/Adldap2/Adldap2/blob/master/docs/models/model.md#setting-attributes
$ldapObject->setDisplayName('Fancy New Displayname');

// Step 3: Save an check return value
if ($ldapObject->save()) {
    echo "// Displayname successfully updated.";
} else {
    echo "// There was an issue updating this user.";
} 

Further documentation: https://github.com/edvler/yii2-adldap-module/blob/master/docs/CREATE_MODIFY_DELETE_OBJECTS.md


Testing

This section is only for developers, that may extend the functionality.

These test classes exists:

For the UserModelTest test it's neccessary to setup the deep integration as described here: https://github.com/edvler/yii2-adldap-module/blob/master/docs/USAGE_WITH_USER_MODEL.md

Usage:

  • Use the phpunit from yii2. Its placed in vendor\bin\phpunit.
  • Create the config class tests\base\TestConfig.php from the template tests\base\TestConfigSample.php.

Start the tests in windows with:

// WARNING!! NOT RUN ON PRODUCTION!!
// TABLES ARE TRUNCATED AND ACTIVE DIRECTORY IS MODIFIED!
// TAKE A LOOK AT THE SOURCE CODE BEFORE RUNNING THE TESTS.
cd vendor/edvlerblog/yii2-adldap-module
..\..\bin\phpunit -v --debug
..\..\bin\phpunit --testdox
