如何用passport-saml修复SLO，它在第一次注销时有效，但在以后的注销中不起作用

Question

我必须将应用程序连接到我公司的ADFS服务器。我正在为SSO和SLO使用Passport-saml。 SSO有效，并且SLO仅在首次注销时有效。每当用户注销时，我都在尝试使SLO正常工作。

我一直在高低寻找这个问题的解决方案，但是它回避了我。这是详细信息：

我会清除浏览器中的cookie，以便从头开始。
我登录到我的应用程序，该应用程序重定向到ADFS的登录页面
输入用户凭据，然后ADFS重定向回我的应用程序主页
我注销了我的应用程序，并且将请求发送到ADFS服务器，这终止了我在本地和ADFS上的会话，然后将我重定向回我的应用程序的主页
我再次登录，可以正常使用
我注销，但是这次我被发送到ADFS服务器的注销页面。

进一步检查显示，ADFS没有清除其cookie，因此ADFS会话保持活动状态。

我使用Firefox的SAML查看器插件来观察正在发生的事情，这是我的发现：

成功注销时：

SAML：

未发送SAML

您将看到，成功注销后，ADFS会将cookie设置为清除它们，而失败注销则不会。另外，失败的注销不会发送SAML注销请求。

最后，当我清除浏览器中的cookie时，第一个登录/注销会话将再次按预期工作，而所有后续注销均将无法进行。我可以看到Cookie保留在后续注销中，因为ADFS没有收到SAML注销请求。我只是不了解在第一次注销时如何工作，而在随后的注销中却不知道。我已经检查过护照saml的代码，但似乎找不到问题。

任何帮助都会很棒。
