python-ldap连接dn时报错

Question

要连接的用户的DN：uid=root,ou=People,dc=demo,dc=com
baseDN:dc=demo,dc=com
10.10.16.14上安装了openldap

代码：

#!/usr/bin/python2.7
# -*- coding: utf-8 -*-
import ldap

if __name__ == '__main__':
    ldapPath = "ldap://10.10.16.14"
    baseDn = "dc=demo,dc=com"
    ldapUser = "root"
    ldapPasswd = "1"
    l = ldap.initialize(ldapPath)
    # Set LDAP protocol version used
    l.protocol_version = ldap.VERSION3
    l.simple_bind_s(ldapUser,ldapPasswd)
    print "bind success"

运行后报这个：
