Python ldap3 LDAPSocketOpenError无法发送消息，套接字未打开

Question

我用Python编写代码，ldap3试图在CentOS上的OpenLDAP中创建一个用户。 我的本地开发计算机运行的是Windows 8 64bit。 下面是我的代码。

from ldap3 import Server, Connection, ALL

# define the server
s = Server('ldap://ldap.abcd.com:389', get_info=ALL)  

# define the connection
c = Connection(s, user='cn=Manager,dc=mydomain,dc=com', password='Super1')

# perform the Add operation
c.add('uid=user3,ou=People,dc=abcd,dc=com',['person','organizationalPerson','inetOrgPerson', 'posixGroup', 'top','shadowAccount'], {'givenName': 'user3firstname','sn': 'user3lastname', 'uidNumber' : 520,'gidNumber' : 521,'uid': 'user3','cn': 'user3user3lastname'})

# close the connection
c.unbind()

服务器和连接类工作正常。我想是因为如果我只运行这两个语句，它不会在下面生成错误。

Answer 1

在添加用户之前，必须绑定连接。在add语句之前尝试c.bind（）。
