您好
我合并了来自 LDAP 和本地论坛的用户。当本地论坛用户注销时，他会收到以下错误
抱歉，将此移至 Support，我们需要更多信息。

您能否检查一下是否设置了
DISCOURSE_SAML_LOG_AUTH: true
DISCOURSE_SAML_DEBUG_AUTH: true
并查看 /logs 中的日志？
你好
我也无法通过 SAML 登录，但这在另一个帖子里……但本地用户会遇到登出错误 
.. 在之前的论坛安装中，SAML 和 LDAP 都工作正常，并且 SAML 也正常，因为其他服务运行顺利。所以我猜我可能在设置中遗漏了什么
还有一个错误：SiteSetting.enable_personal_messages … 日志中只有这些。这是全新安装的……
我现在也勾选了 log_auth，并进行了几次登录和登出，我得到了以下错误：

(saml) 身份验证失败！invalid_ticket: OneLogin::RubySaml::ValidationError, 响应的状态码不是 Success

即使我以本地用户身份登录，SAML 也希望注销本地用户，因为它在 LDAP 中找不到用户，所以我收到错误。
您好，我已经成功配置了SAML，可以登录和注销用户，但它也试图注销未通过SAML登录的用户，导致用户注销时出现错误页面。
你好
当用户合并时，团队中的一些人使用 SAML 登录论坛，而另一些人则本地登录。当人们在没有 SAML 的情况下登录并在注销时收到错误，并且我在本地用户注销时在日志中看到以下内容：

以下屏幕欢迎已注销的本地用户。
我们在论坛上遇到了类似的情况，之前启用了 SAML，但现在已禁用。但是，saml_slo_target_url 仍然配置着，Discourse 一直在使用它。
因此，修复方法应该是仅当 SAML 插件已启用并且用户最初是通过 SAML 登录时才使用它。
