title: Bind settings for LDAP authentication for moodle
body: <p>I am now trying to configure for the LDAP authentication in <code>/admin/auth_config.php?auth=ldap</code>.</p>
  
  <p>I would like to know what the <code>Bind settings</code> does? Is it necessary to fill in the DN and Password under <code>Bind settings</code> for LDAP to work?</p>
  
  <p>And I have encountered an error code <code>auth_ldap_noconnect</code> when trying to sync the users through LDAP from the cron script. What could be the causes for this error?</p>
