我认为我的问题归结于 OpenLDAP。我希望我的用户能够使用 Pidgin 聊天客户端更改密码。目前，我必须设置他们的密码，这很麻烦。OpenLDAP 运行良好，我的配置如下。
当用户尝试更改密码时，他们会收到来自 Pidgin 的 403 禁止错误。当收到此错误时，OpenLDAP 日志中没有任何反应，这让我认为请求从未到达那里。这是来自 Pidgin 的日志：
(14:08:01) jabber: Sending (ssl) ([email protected]/b660f5a6): <iq type='set' id='purple711c2157' to='xx.com'><query xmlns='jabber:iq:register'><username>test.account</username><password>22</password></query></iq>
(14:08:01) jabber: Recv (ssl)(302): <iq type="error" id="purple711c2157" from="xx.com" to="[email protected]/b660f5a6"><query xmlns="jabber:iq:register"><username>test.account</username><password>22</password></query><error code="403" type="auth"><forbidden xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/></error></iq>
这是我的 slapd.conf：

有人有主意吗？

这里的问题不是 Pidgin 或 OpenLDAP - 而是 Openfire（我根据你的标签推断你正在使用它）。它不支持以任何方式更改外部 LDAP 用户；直接更改密码仅适用于本地定义的用户。
看这里：
Openfire 将 LDAP 目录视为只读。
