You don' t provide much detail on what you are trying to achieve or where the error is displayed but it could be: -You are using a simple bind when an authenticated (regular) bind to LDAP is required - The account you are using to bind to the LDAP directory does not have adequate permissions - The connection method you are using is not supported (i.e. LDAPS is required)

use regular bind instead of simple, make sure you authenticate with a user that is authorized to make LDAP queries

regular bind works. thanks.
