ldap_sasl_bind函数的示例？

import ldap

def ldap_sasl_bind_example():
    try:
        # 连接LDAP服务器
        ldap_conn = ldap.initialize('ldap://ldap.example.com')
        
        # 设置SASL机制和用户凭据
        ldap_conn.sasl_bind('PLAIN', 'username@example.com', 'password')
        
        # 进行身份验证
        result = ldap_conn.whoami_s()
        
        # 打印身份验证结果
        print("Authentication successful. User: " + result)
        
        # 关闭LDAP连接
        ldap_conn.unbind_s()
        
    except ldap.LDAPError as e:
        print("LDAP Error: " + str(e))
