simplesamlphp 中的重定向过多

Question

添加新应用程序以访问 saml 时，我遇到了这个问题。

SSOService.php:1 获取https://saml.testing.net/www/saml2/idp/SSOService.php?spentityid=newapp&cookieTime=1459920375

net::ERR_TOO_MANY_REDIRECTS

在我的本地我没有遇到任何问题，但是当我将代码复制到登台服务器时，它会显示 ERR_TOO_MANY_REDIRECTS 错误，继续重定向，并且无法显示 saml 登录页面。带有负载平衡器的登台服务器，这会导致错误吗？

谢谢。

Answer 1

在我的例子中，SameSite=None cookie 属性是罪魁祸首。SameSite=无cookie 必须与安全属性一起使用！

解决方案：

'session.cookie.secure' => true // config.php

如果您的服务在反向代理之后运行并且未通过 https 运行，则您还需要定义 URL 架构：

'baseurlpath' => 'https://my.url.com/<path_to_simple_saml>' // indicating the https schema (config.php)
