GSSException:尝试使用kerberos ti进行身份验证时，找不到1.2.840.113554.1.2.2的凭据

Question

我正在尝试对一个Jenkins实例进行身份验证，该实例配置为使用pythonrequests\u negotiate使用Kerberos SSO。身份验证失败，服务器端出现下面报告的堆栈跟踪。

klist确认我有一张有效的票证。我可以使用启用了GSS-API Kerberos SPNEGO功能的cURL 7.59.0成功进行身份验证：

curl --negotiate --user : -k --verbose https://myjenkins.example.com/

我也尝试了requests_gssapi.HTTPSPNEGOAuth()，但却得到了与requests_negotiate相同的失败。

如有任何关于调试的建议，我们将不胜感激。这对我来说是个陌生的领域。

我的Python代码：

^{pr2}$

服务器上显示的堆栈跟踪：

我在使用npm kerberos包时遇到了同样的错误，我通过显式要求SPNEGO协议来解决它，因为错误消息指出kerberos票证中缺少此协议的凭据。你说它对curl和SPNEGO有效，但对请求都不适用_negotiate.HTTPNegotiateAuth（）也没有要求_斯普希特普特(). 我无法从文档或源代码中看出requests\u negotiate使用哪种机制，所以我现在还是坚持使用requests_gssapi，这也广泛地使用了日志记录。你从那个日志中得到了哪些信息？在

我觉得这更多的是一个评论，但我没有这个名誉去评论。在
