Why always get error like this? i've been configured as well

[Jeffrey Bostoen]

From the iTop web server: can you connect to 10.210.20.100 - port 389? (mind that this is deprecated, modern implementations should use LDAPs which is typically on port 636)

[Afie Yudha Triadi]

yes i can ping and telnet server LDAP and on my local with xampp i can login with same ldap server.
i don't know why on my staging server can't login.

Can you share the relevant config? Definitely censor sensitive info.

'authent-ldap' => array (
    'host' => '10.210.xx.xxx',
    'port' => 389,
    'default_user' => 'uid=admin,ou=people,dc=xxxxx,dc=co,dc=id',
    'default_pwd' => 'xxxxx',
    'base_dn' => 'ou=people,dc=xxxxx,dc=co,dc=id',
    'user_query' => '(&(uid=%1$s))',
    'options' => array (
      17 => 3,
      8 => 0,
    ),
    'start_tls' => false,
    'debug' => true,
    'servers' => array (
      'MySecond-LDAP-Server' => 
      array (
        'host' => '10.210.xx.xxx',
        'port' => 389,
        'default_user' => 'uid=admin,ou=people,dc=xxxxx,dc=co,dc=id',
        'default_pwd' => 'xxxxx',
        'base_dn' => 'ou=people,dc=xxxxx,dc=co,dc=id',
        'user_query' => '(&(uid=%1$s))',
        'options' => 
        array (
          17 => 3,
          8 => 0,
        ),
        'debug' => true,
      ),
    ),
),

This is my config on my itop local and staging server

[Jeffrey Bostoen]

The message (can not contact LDAP server) would be a bit misleading if it's a credentials issue; but have you tried using 'default_user' => 'username' or 'domain\username'?

[Afie Yudha Triadi]

yes, i've tried using default user => 'admin' and same error.
when i tried with same config before like above on my local is works
