上面是我将发送给AD的查询片段。当我输入一个确切的姓氏时，它可以正常工作。但是，当我输入部分姓氏时，我没有得到任何结果。

有人可以告诉我如何对部分名称进行搜索吗？

%不是LDAP filters中的有效通配符，您也无法在VBScript LDAP查询中使用环境变量（%variable%）。具有部分值的过滤器可以这样定义：

(&(objectCategory=person)(objectClass=user)(sn=*something*))

如果要在过滤器中使用变量，则必须使用字符串连接：

"(&(objectCategory=person)(objectClass=user)(sn=" & variable & "))"

如何使用通配符在AD中搜索姓氏？
