Binding only works sometimes

Binding fails ~9/10 times. Not sure if I am improperly using the node-ldapjs client, or if there is a problem with the server I am connecting to.

My code:

var client = ldap.createClient({
  url: 'ldap://main.ad.rit.edu',
});    

client.bind(credentials.username, credentials.password, function (err) {
  if (err) {
    console.log("[ERROR] when binding:");
    console.log(err, err.dn, err.code, err.name, err.message);
  } else {
    ...
  }
}

Output (on failure case):

[ERROR] when binding:
{ [ConnectionError: ldap://main.ad.rit.edu closed]
  dn: [Getter],
  code: [Getter],
  name: [Getter],
  message: [Getter] } '' 128 'ConnectionError' 'ldap://main.ad.rit.edu closed'

Otherwise, when it succeeds, I can run queries and the client functions as expected.

@bhshkh As stated before, it’s likely an issue with the LDAP server you are connecting to and not the node-ldapjs client.

Any update on how to resolve this?
