Question

有一段时间我一直试图通过cfldap更改密码。连接通过SSL和端口636（cfssl_basic）进行，在登录时进行测试。我尝试了以下版本的代码：

<cfset password_new_retyp=charsetEncode(charsetDecode('"'&password_new_retyp&'"','UTF-16LE'),'UTF-8'))>
<!---encoded, decoded password --->
<cfldap action="modify"
    dn="#session.dn_addres#" --- i query this on login
    modifyType="replace"
    attributes="unicodePwd=#password_new_retyp#"
    server="xxxx.xxxx.xxx.xx" --- name of server thet i use on login
    secure = "cfssl_basic" 
    port=636
    username="#session.username#" ---username thet is used on login
    password="#password_old#">  ---- pass before changing

并且错误是这样的：

尝试执行查询时发生错误：[LDAP：错误代码49 - 80090308：LdapErr：DSID-0C0903C5，注释：AcceptSecurityContext错误，数据52e，v23f0]。

我也尝试过这种方法而不用编码密码：

<cfldap action="modify"
    dn="#session.dn_addres#"
    modifyType="replace"
    attributes="password=#password_new_retyp#"
    server="xxxx.xxxx.xxx.xx"
    secure = "cfssl_basic"
    port=636
    username="#session.username#"
    password="#password_old#" >

和eror是一样的：

尝试执行查询时发生错误：[LDAP：错误代码49 - 80090308：LdapErr：DSID-0C0903C5，注释：AcceptSecurityContext错误，数据52e，v23f0]。一个或多个必需属性可能丢失或不正确，或者您无权在服务器上执行此操作。

有什么想法吗？

这是漫长而艰难的道路，但我到了那里。我希望这有助于其他任何人尝试更改密码并实施LDAP密码策略。

是否可以通过cfldap更改密码？
