What does this mean: "unable to send message, socket is not open"?

I'm trying to connect to my ldap server, but it seems to be failing in someway or form:

import csv
from ldap3 import Server, Connection, ALL, NTLM, SUBTREE
import pandas as pd


server = Server('cybertest02.ad.arb.ca.gov', get_info=ALL)
c = Connection(server, user='myusername', password='mypassword')

c.search(search_base = 'o=test',
         search_filter = '(objectClass=inetOrgPerson)',
         search_scope = SUBTREE,
         attributes = ['cn', 'givenName'])

total_entries += len(c.response)
for entry in c.response:
    print(entry['dn'], entry['attributes'])

Error on line 12: where attributes is, unable to send message, socket is not open

Try inserting c.bind() before the c.search() and after the Connection() statements.

According to LDAP3 Docs, you must bind() to establish a new authorization state in the server.

  • As specified in RFC4511 the Bind operation is the “authenticate” operation.

  • When you open a connection to an LDAP server you’re in an anonymous connection state. What this exactly means is defined by the server implementation, not by the protocol.

  • The bind() method will open the connection if not already open.

  • The Bind operation instead has nothing to do with the socket, but performs the user’s authentication.

Also you should use c.unbind() to close the connection.
