红帽全球峰会A.3. Firefox Kerberos 配置故障排除
如果 Kerberos 身份验证不起作用，请为身份验证过程打开详细日志记录。
- 关闭 Firefox 的所有实例。
- 在命令提示符中，导出
NSPR_LOG_*变量的值：export NSPR_LOG_MODULES=negotiateauth:5 export NSPR_LOG_FILE=/tmp/moz.log
export NSPR_LOG_MODULES=negotiateauth:5 export NSPR_LOG_FILE=/tmp/moz.logCopy to Clipboard Copied! Toggle word wrap Toggle overflow - 从该 shell 重新启动 Firefox，再访问失败 Kerberos 身份验证的网站。
- 检查
/tmp/moz.log文件中是否有消息中带有 nsNegotiateAuth 的错误消息。
Kerberos 身份验证会出现几个常见错误：
- 没有找到凭证
-1208550944[90039d0]: entering nsNegotiateAuth::GetNextToken() -1208550944[90039d0]: gss_init_sec_context() failed: Miscellaneous failure No credentials cache found

Toggle word wrap Toggle overflow 这意味着没有可用的 Kerberos 票据（这意味着它们已过期或未生成）。要解决这个问题，请运行 kinit 来生成 Kerberos 票据，然后再次打开网站。- 在 Kerberos 数据库中找不到服务器

Toggle word wrap Toggle overflow 这意味着浏览器无法联系 KDC。这通常是 Kerberos 配置问题。正确的条目必须位于/etc/krb5.conf文件的 [domain_realm] 部分，以识别域。例如：.example.com = EXAMPLE.COM example.com = EXAMPLE.COM
.example.com = EXAMPLE.COM example.com = EXAMPLE.COMCopy to Clipboard Copied! Toggle word wrap Toggle overflow - 日志中没有错误
- HTTP 代理服务器可以剥离 Kerberos 身份验证所需的 HTTP 标头。尝试使用 HTTPS 连接到站点，这将允许请求通过未修改的传递。
