使用ldap对接linux

使用LDAP对接Linux是一种常见的用户认证方式。可以参考中介绍的配置Linux使用LDAP用户认证的方法进行操作。下面提供一个简单的示例代码供参考：

import ssl
from ldap3 import Server, Connection

SERVER = "ldap.example.com"
USER = "cn=admin,dc=example,dc=com"
PASSWORD = "password"
BASE_DN = "dc=example,dc=com"

def ldap_connect():
    server = Server(SERVER, port=636, use_ssl=True, get_info="ALL",
                    tls=ssl.TLS(validate=ssl.CERT_REQUIRED, version=ssl.PROTOCOL_TLSv1, ciphers="ALL"))
    conn = Connection(server, user=USER, password=PASSWORD)
    conn.bind()
    return conn

def ldap_search(username):
    conn = ldap_connect()
    conn.search(BASE_DN, f"(uid={username})")
    return conn.entries

def ldap_authenticate(username, password):
    conn = ldap_connect()
    conn.search(BASE_DN, f"(uid={username})")
    if len(conn.entries) == 1:
        user_dn = conn.entries
