我尝试使用Kerberos上的内置SPNEGO身份验证器为Tomcat 7.0.69配置WebSSO。当我访问应用程序时，会弹出HTTP BasicAuth对话框，并在catalina.out中写入调试条目（见下文）。
我的密钥表文件 sso.keytab 包含在我的AD-Server上注册的主体（通过ktpass.exe＆amp; setspn.exe）。
我为Kerberos启用了调试模式，但我找不到问题。它只是在输入注销的某个时刻停止。你有什么想法，在哪一步认证停止，可能是什么原因？任何帮助表示赞赏！
catalina.out中

感谢T-Heron，我找到了解决方案。密钥表文件是使用错误的加密类型生成的。对于Windows7 / 10，在我的环境中，必须明确设置为 AES256-SHA1
正确的ktpass通话：
ktpass -out D:\TEMP\sso.keytab -mapuser MYUSER -princ HTTP/my.host.com@MY.DOMAIN -ptype KRB5_NT_PRINCIPAL -kvno 0 -crypto AES256-SHA1 -pass ****
非常感谢您的支持!!!
