GSSException：尝试使用kerberos票证进行身份验证时，找不到以下凭证：1.2.840.113554.1.2.2

标签： python jenkins kerberos

我正在尝试通过Python request_negotiate身份验证到配置为使用Kerberos SSO的Jenkins实例。身份验证失败，下面报告的堆栈跟踪显示在服务器端。

klist确认我有有效的票证。我可以使用启用了GSS-API Kerberos SPNEGO功能的内部版本成功使用cURL 7.59.0进行身份验证：

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

我也尝试过requests_gssapi.HTTPSPNEGOAuth()，但失败的原因与requests_negotiate相同。

关于调试此问题的任何建议，我们将不胜感激。对我来说这是陌生的领域。

我的Python代码：

import requests
import requests_negotiate

auth = requests_negotiate.HTTPNegotiateAuth()
response = requests.get('https://myjenkins.example.com', auth=auth, verify=False)
print (response.content)

出现在服务器上的堆栈跟踪：

答案 0 :(得分：0)

使用npm kerberos软件包时，我遇到了相同的错误，我通过明确要求SPNEGO协议解决了该错误，因为错误消息指出Kerberos票证中缺少该协议的凭据。您说它适用于curl和SPNEGO，但不适用于request_negotiate.HTTPNegotiateAuth（）或request_gssapi.HTTPSPNEGOAuth（）。我从文档或源代码中看不到requests_negotiate使用哪种机制，因此我现在将坚持使用requests_gssapi，这也大量使用了日志记录。您从那条日志中得到哪些日志消息？

我觉得这更多是评论，但我没有评论的声誉。
