Subject [jira] [Updated] (HTTPCLIENT-1545) Possible infinite loop when WindowsNegotiateScheme authentication fails
Date Sun, 17 Aug 2014 06:02:18 GMT

     [ https://issues.apache.org/jira/browse/HTTPCLIENT-1545?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ka-Lok Fung updated HTTPCLIENT-1545:
------------------------------------

    Attachment: HTTPCLIENT-1545.patch.diff

Here's my patch for the issue. I also added a unit test. {{mvn test}} passes 100% on my developer
box.

Even though I haven't tested it first hand, I believe this issue is reproducible on any Windows
system, even when your machine isn't a member of a domain. If my unit test is run on a non-Windows
machine, the unit test will be ignored.

Any comments and feedback is welcome.

> When {{WindowsNegotiateScheme}} authentication fails, it's possible for HttpClient to
retry the authentication in an endless loop because the {{continueNeeded}} flag is not set
to {{false}} when authentication fails.
> One possible way of causing authentication to fail is to use a service principle name
that is outside your Windows domain (e.g., HTTP/EXAMPLE.COM).
