我按照guide将cas与Windows AD集成。
几天前它在每个浏览器上运行良好。但它不仅适用于IE,当我使用firefox浏览器时只向服务器发送“Negotiate TlRMTVNTUAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAADA = A”,然后浏览器返回cas登录页面。
最近才在生产环境中发现此问题。我有一个具有相同配置的测试环境,但它一直运行到现在。
我知道当kerberos票不在本地缓存时,浏览器会发送“Negotiate TlRMT ......”。但是我可以看到带有klist命令的票证,它适用于IE意味着 票很好。
我想这可能是由于Windows客户端或广告服务器的某些配置引起的,有人可以给我一些建议吗,tks!
“https://1056-app.test.com”已添加到 firefox上的“network.negotiate-auth.trusted-uris”。我也试过 重新安装firefox,而不是工作。

找到了根本原因。因为我们对dns使用cname,而cname与spn地址不匹配。
我使用此命令打开firefox协商调试日志。link
set NSPR_LOG_MODULES=negotiateauth:5
set NSPR_LOG_FILE=C://firefox.log
./firefox.exe

1.将DNS更改为A类型
2.修改浏览器以禁用kerberos cname查找。 Chrome link。 Firefox不支持。
