Example of configuration and a use case

Considering yii2-app-basic:

Configure the component in your configuration file and change user identity class
'components' => [
    ...
    'ldapAuth' => [
        'class' => '\stmswitcher\Yii2LdapAuth\LdapAuth',
        'host' => 'your-ldap-hostname',
        'baseDn' => 'dc=work,dc=group',
        'searchUserName' => '<username for a search user>',
        'searchUserPassword' => '<password for a search user>',

        // optional parameters and their default values
        'ldapVersion' => 3,             // LDAP version
        'protocol' => 'ldaps://',       // Protocol to use           
        'followReferrals' => false,     // If connector should follow referrals
        'port' => 636,                  // Port to connect to
        'loginAttribute' => 'uid',      // Identifying user attribute to look up for
        'ldapObjectClass' => 'person',  // Class of user objects to look up for
        'timeout' => 10,                // Operation timeout, seconds
        'connectTimeout' => 5,          // Connect timeout, seconds
    ],
    ...
    
    'user' => [
        'identityClass' => '\stmswitcher\Yii2LdapAuth\Model\LdapUser',
    ],
    ...
]
Update methods in LoginForm class
use stmswitcher\Yii2LdapAuth\Model\LdapUser;

...

public function validatePassword($attribute, $params)
{
    if (!$this->hasErrors()) {
        $user = LdapUser::findIdentity($this->username);

        if (!$user || !Yii::$app->ldapAuth->authenticate($user->getDn(), $this->password) {
            $this->addError($attribute, 'Incorrect username or password.');
        }
    }
}

...

public function login()
{
    if ($this->validate()) {
        return Yii::$app->user->login(
            LdapUser::findIdentity($this->username),
            $this->rememberMe
                ? 3600*24*30 : 0
        );
    }
    return false;
}
Verify that user belongs to LDAP group

If you need also need to check if user is a member of certain LDAP group, use one more parameter for the authenticate function: `php Yii::$app->ldapAuth->authenticate($user->getDn(), $this->password, 'cn=auth-user-group') `

Now you can login with LDAP credentials to your application.
