【问题描述】：

我正在尝试运行试图建立连接的代码：

server = Server(host='localhost', port=33389, use_ssl=False, get_info=ALL)
conn = Connection(server, user='uid=admin,ou=people,dc=example,dc=org', password=user-pass, raise_exceptions=False, authentication=SIMPLE)
print(server.info)
print(conn)

以下是错误详情：

None
ldap://localhost:33389 - cleartext - user: uid=admin,ou=people,dc=hadoop,dc=apache,dc=org - not lazy - unbound - closed - <no socket> - tls not started - not listening - SyncStrategy - internal decoder

【解决方案1】：

在读取信息之前，您必须使用 conn.bind() 方法打开连接。

【解决方案2】：

如果您使用了 print(conn.result)，它将显示更多详细信息以及“描述”和“消息”，您可以在其中找到终止它的正确原因。

示例：- {'dn': u'', 'saslCreds': None, 'referrals': None, 'description': 'inappropriateAuthentication', 'result': 48, 'message': u'Inappropriate authentication', 'type': '绑定响应'}

{'dn': u'', 'saslCreds': None, 'referrals': None, 'description': 'success', 'result': 0, 'message': u'', 'type': '绑定响应'})
