我正在尝试使用 Kerberos 实现 Jmeter 脚本(jmeter 版本 5.1(以实现 SSO 功能。 我已经在 krb5 和 jass conf 文件中完成了设置，并且还更新了 HTTP 授权管理器，其中包含域、领域和机制作为 Kerberos。
运行脚本时，脚本不会在 URL 中输出 SAML 响应。检查 jmeter 日志会给出以下错误：

不幸的是，您的问题没有足够的细节来猜测失败原因，接下来请考虑添加以下屏幕截图：
- HTTP 请求采样器
- HTTP 授权管理器
krb5.conf和jaas.conf文件的内容拥有更详细的日志也是有益的，将下一行添加到 log4j2.xml 文件中：
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />并将
sun.security.krb5.debug系统属性设置为true
